Took about 12 hours. PVA glue + watercolour, correction fluid, Sharpie on acetate sheets.
Boy, I sure hope that comes across as two spiralling blood fists.
The trick is to scan at way more than 600dpi and hope your computer doesn't explode from lack of RAM. XD
Here are a couple snaps I took mid-way, if you wanted to see the assembly in RL: https://twitter.com/primaeros/status/490977532250828800

I didn't see the fists at first, but after your mention, yep now I do. Holy cow I love your scanner because the details in this are shown so well. It's almost as if the piece is popping out of the screen!
