Here's a couple of pics of my Mega connected to both the bma180 and itg3200 that Santa brought for me.

On the left is a logic level converter with the bma180 in the middle and the itg3200 on the right.

Here's a close up of just the bma180 and the itg3200.

Example code can be found on github. itg3200_demo.pde and bma180_demo.pde.

Thanks to Fabio Varesano for the itg3200 code and m.ryandesign for the bma180 code.
