Fish eye/Wide angle/Macro

The other day I bought a new lens converter-a wide angle/fisheye + macro. I'm not sure the macro is that great yet as it can only focus on a really really small area (in comparison to macro photos I've seen, some still have quite a bit of area in focus). But the wide angle and fish eye part of it seems good.
Here are some first experiments with it...
