Seb Lee-Delisle made this cool particle system using an Arduino board and an 8×8 LED array. He writes:
The only real trick here is that I’m working internally with a much higher resolution that the actual 8×8 grid, and then rounding to the nearest pixel when displaying each particle. This gives a really smooth movement. I’m only actually lighting one LED per particle but due to the Persistence of Vision (POV) effect it looks like there are more.

Hey,
I have a great link for an interview of Dale Dougherty at the SXSW Interactive Festival, filmed in the famous Austin City Limits Studio. Dougherty is the editor of CRAFT and MAKE magazines and founder of Maker Fair. The interview focuses on Dougherty’s views on how building do it yourself (DIY) communities can be similar to building online communities (Blogging). Here is a link to the video from the website of the show Docubloggers on the PBS station KLRU in Austin, Texas. Enjoy!
