I found this little guy I kit-bashed together years ago when I was packing to move. His body is a tank turret, and there are some Gundam joints in there. The paint job makes me cringe now, but I like the overall design.
Another quick project I did the day before Burningman. We didn't have any flashlights so I made these so we could see in the porta-potties at night. Mine broke the second night, so I had lots of thrilling adventures.
