Ooh! Well, see, this is some little teeny thing I got from a friend at work. It's exactly what it looks like, maybe a little smaller, and it rolls across smooth surfaces. I honestly have no idea what it really is.
Regarding focus, I was using my Canon PowerShot, which only does auto-focus, and I was really close to it with my GorillaPod. I just wanted to capture it, and wasn't thinking much about lighting, detail or reflections.
Having said all that, I'm actually reading a lighting book right now and getting some fantastic ideas for the future.
