I added a "jelly lens" wide angle for the front, basically they are stick on wide angle lenses, they go for a couple bucks on ebay, they can be glued permanently on. This camera has a built in rechargable batter that will record for ~2 hours. For your nefarious needs, it can do sound activated recording, I wont give you any ideas. It'll do about 40 minutes per gig, so a 2 gig card will fill before the battery, they can be sensitive to cards, so you want a class 6 card microSD card. It'll also act as a webcam, I have not tried that yet. There's a bunch of reviews online, because they are super cheap, small and light, they are getting strapped onto all sorts of things, lots of info on them on the RC airplane forums.
This is what you get for 15 $, I put quarters on/around it for scale, sorry my iphone takes horrible pictures



Sample video of with and without the jelly lens, you can tell it makes the view quite a bit wider. I will try to get some helmetcam footage this week to test out the video and sound. The sound will pick up wind, so I'll probably have to use some black or friction tape over the microphone hole. There's lots of videos on youtube from these things already.
