Ordinary DSLR cameras too big and bulky for you? Check out the CHOBi CAM ONE, a DSLR-style toy camera the size of an eraser that actually has lenses you can swap in and out. It shoots 1600×1200 still photos and VGA video at 30 frames per second.

The camera supports microSDHC memory cards of up to 32GB, and costs ¥9,800 (~$118) with a basic lens from the JTT Online Shop (currently it’s only available in Japan).
