Self-portrait on a bicycle
Ah, this is nice: a collection of many videos all taken from exactly the same angle -- anchored to the handlebars of a bike -- collapsed and blended into one.
Spooky to watch. It sorta feels like he's riding through time itself. Ah, this is nice: a collection of many videos all taken from exactly the same angle -- anchored to the handlebars of a bike -- collaps... more -
Top 5 benefits of FPGA technology
Field-programmable gate array (FPGA) technology continues to gain momentum, and the worldwide FPGA market is expected to grow from $1.9 billion in 2005 to $2.75 billion by 20101. Since its invention by Xilinx in 1984, FPGAs have gone from being simple glue logic chips to actually replacing custom application-specific integrated circuits (ASICs) and processors for signal processing and control applications. Why has this technology been so successful? This article provides an introduction to FPGAs and highlights some of the benefits that make FPGAs unique.
Top Five Benefits:
1. Performance
2. Time to Market
3. Cost
4. Reliability
5. Long-Term Maintenance
At the highest level, FPGAs are reprogrammable silicon chips. Using prebuilt logic blocks and programmable routing resources, you can configure these chips to implement custom hardware functionality without ever having to pick up a breadboard or soldering iron. You develop digital computing tasks in software and compile them down to a configuration file or bitstream that contains information on how the components should be wired together. In addition, FPGAs are completely reconfigurable and instantly take on a brand new “personality” when you recompile a different configuration of circuitry. In the past, FPGA technology was only available to engineers with a deep understanding of digital hardware design. The rise of high-level design tools, however, is changing the rules of FPGA programming, with new technologies that convert graphical block diagrams or even C code into digital hardware circuitry.
FPGA chip adoption across all industries is driven by the fact that FPGAs combine the best parts of ASICs and processor-based systems. FPGAs provide hardware-timed speed and reliability, but they do not require high volumes to justify the large upfront expense of custom ASIC design. Reprogrammable silicon also has the same flexibility of software running on a processor-based system, but it is not limited by the number of processing cores available. Unlike processors, FPGAs are truly parallel in nature so different processing operations do not have to compete for the same resources. Each independent processing task is assigned to a dedicated section of the chip, and can function autonomously without any influence from other logic blocks. As a result, the performance of one part of the application is not affected when additional processing is added.
The adoption of FPGA technology continues to increase as higher-level tools evolve to deliver the benefits of reprogrammable silicon to engineers and scientists of all expertise. Field-programmable gate array (FPGA) technology continues to gain momentum, and the worldwide FPGA market is expected to grow from $1.... more -
Daily Inspiration: Flight404 - videoartista che usa Processing
Flight404, aka Robert Hodgin, è un artista americano che crea video utilizzando unicamente Processing, un linguaggio di programmazione open-source.
Nella pagina segnalata ci sono stream in alta definizione.

White Glove Tracking
On May 4th, 2007, we asked internet users to help isolate Michael Jackson's white glove in all 10,060 frames of his nationally televised landmark performance of Billy Jean. 72 hours later 125,000 gloves had been located. wgt_data_v1.txt (listed below) is the culmination of data collected. It is released here for all to download and use as an input into any digital system. Just as the data was gathered collectively it is our hope that it will be visualized collectively. Please email links to your apps, video, source code, and/or screen shots to evan[at]eyebeam[dot]org. Work will be exhibited in an online gallery and depending on popularity and interest potentially in a forthcoming physical gallery exhibition as well. Huge thanks to everyone that contributed to the data collection.
For more information please check out the top data contributers, the about page, and the original data entry applet (no longer in use). To view visualizations of this data check out the gallery. Example source code for getting started can be downloaded below (available as Processing and Open Frameworks projects).

Sheep Market
"TheSheepMarket.com is a collection of the first 10,000 sheep made by workers on Amazon's Mechanical Turk. Workers were paid 0.02 ($USD) to "draw a sheep facing to the left." Animations of each sheep's creation may be viewed at TheSheepMarket.com."
And if browsing through 10,000 hastily drawn sheep isn't enough for you, you can download Aaron Koblin's 42-page thesis on the project to have him "explore the discourse surrounding commoditization of human labor, the connotations of sheep, and the techniques of visualizing governance within the realm of media art." Go on!

Email Map
Project Description:
This Email Map, created by Christopher Baker, is a piece of custom designed software capable of rendering the relationships between Christopher and individuals in his address book by examining the TO:, FROM:, and CC: fields of every email in his email archive. The intensity of the relationship is determined by the intensity of the line. The tool allows one to explore different relational groupings and periods of time, revealing the temporal ebbs and flows in various relationships. In this way, this tool is a veritable self-portrait, a reflection of Christopher's associations and a way to locate himself at various points in history.
As the author explains: "Email became an integral part of my life in 1998. Like many people, I have archived all of my email with the hope of someday revisiting my past. I am interested in revealing the innumerable relationships between me, my schoolmates, work-mates, friends and family. This could not readily be accomplished by reading each of my 60,000 emails one-by-one".
This project can be viewed as a large scale static print (40"x40" archival inkjet) or as an up-to-date dynamic visualization. The interactive program is written in Java and uses Processsing, MySQL and various other libraries. The software includes a custom IMAP email client and a VCF address book parser, which enables the inclusion of VCard photos. This particular visualization strategy was influenced by similar circular relational structures such as CAIDA, SCHEMABALL, GNOM, etc. Much of my initial email visualization research was influenced and inspired by the work of Judith Donath's Sociable Media Group at MIT - particularly the work of Fernanda Viegas.

Driving Down California Street
It doesn't look like it at first glance, but this is video footage of driving down California Street in San Francisco. The video was taken with the iSight on my MacBook and abstracted in real time using Processing. The drive was at night, hence the deep contrast and strong colors.
