For those interested in checking out some of the hardware or software used during the talk, here are some useful links: Main Arduino Project Page: http://www.arduino.cc/Arduino Playground (lots of hardware/software examples): http://www.arduino.cc/playground/Firmata: http://www.firmata.org/wiki/Main_Pagehttp://arduino.cc/en/Reference/FirmataPyduino: http://code.google.com/p/pyduino/Places to Get Kits and Hardware: http://www.adafruit.com/http://www.sparkfun.com/http://liquidware.com/ (I've not bought anything from them personally, but they have some interesting Arduino compatible boards) Also if you're interested in some of the code used during the talk, I've posted some of the demos I did at the end up on github: http://github.com/jsnyder/jbsnyder_tools/tree/masterYou'll probably need to install a few modules to make them work including wx, multiprocessing, matplotlib and numpy (in addition to pyduino from above). The mouse demo also uses a little Objective C program to move the mouse around, compile instructions for that are in the movemouse.m file. Less
