I don't know if you can call it circuit bending, but I think it's somewhere close to it.
First project was to mod the Beep-it optical theremin by Michael Una (http://una-love.com/munablog/) by adding a fan and a pot to control it. The pot does not only control the speed of the fan, but also modifies the sound a bit. it's a bit like the Synth Fan by Gieskes, only this one uses the fan to modulate the sound, and not as an oscillator. http://gieskes.nl)
The second one is also a really simple one, I took one of those lighters that play you some kind of 1 bit tune when you press the button (for Elisa in this case), and added a pot to control the voltage that get's fed through the circuit. I tried to find some more bending point, but on a circuit which consists of one transistor and some kind of microchip, there's not lot you can do. Still it produces some weird noise, which is fun!
here's a video of the devices in action:

The video shows the beep-it thing for the most part, in the end you get a glimpse of the second one.
The music you can hear at the beginning was made with samples taken from both devices, I only added the bass drum and the synth that kicks in after a couple of seconds.
Let me know what you think about it!
