Neocubes and a new flash

These are called Neocubes. They're little magnets of about 5 mm in diameter and are quite addictive.
You can try to build anything with them, but it is quite frustrating since they're never rotated quite the way you want them to be and then they jump to another magnet. It is almost impossible to remove only one, cause they stick together like a chain.

In the reflection, you can see the 2 halves of my macro-ring flash (Canon MR-14EX Macro Ring Lite) and the flash from the left comes from the Speedlite 430 EX-II which can now operate wireless in combination with this flash.

I used the 18-55 kitlens, since it's got a 58 mm filter-ring for the MR-14EX, but I don't like the bokeh of that lens. Maybe I can make/find an adapter for the 52mm filter-size of the 50mm lens.

This is the other flash-unit operating wireless.
