I used an Flipcam(~$80) mounted on a cheap camera-stand($30). recorded all the demos separately. Then used iMovie to clip them down as short as possible and then used the iMovie text transitions to create the Chapter text. Finally I used youtube's free music from their AudioSwap feature.

Note: Some of the mini-clips are slightly sped up to make them less boring. Which I think lends a subtle exaggerated energy to the scenes.
