I found this yesterday on notcot and thought it was a bloody amazing and a totally excessive ingenious piece of design/sculpture. There are very few things that exist or are made and designed just to be cool but this is one of them. Requiring a magnetic key to begin the disassembly process the 40lb 8x4x5inch block breaks down into a 125 piece puzzle that can be remade into a single shot 45 caliber muzzle loading pistol. Designed by GarE Maxton it took over a year to make and looks like the worst kind of toy you find in a Christmas cracker but ridiculously more complicated, just looking at it makes my brain itch. Check out this video though to see it in action.
