Being tied up with work. Hopefully I can get some more posts up on a regular basis.
Anyways, here's something cool to share. The Japanese company Gizmon has two lens that you can attach to your iPhone. One is the fish-eye (about 40-50 USD), and the other is the wide & macro (about 20-30 USD).
The wide & macro lens is actually two lens attached together. When two lens are together, it is wide angle. Take off the wide angle lens attachment, it becomes macro.
The lens are mounted with a magnet to a mount that you tape to your iPhone. If you don't want to tape directly, you can always tape the mount to an external case.
Pair these together with some camera apps, and you can do some fun photography with your iPhone.
