Man, these things look like so much fun. Very nice work. 
Some day...
They are lots of fun for sure. I've learnt a lot about everything VPIN from initial design, construction, to setting up all the software. In particular I've managed to get my head around the back glass editing tool. Using that together with Photoshop allows me to customize the back glass files for correct fit, DMD setup etc. I wasn't happy with the all 3D printed coin plate so I'm re-doing that partly in sheet metal and partly in 3D printed parts. I will post up that in detail as I work through it. Here's a short video for Malenko since he's doing a The Machine: Bride Of Pin-Bot restore/convert to VPIN. The artwork is probably what I like most about that game, especially the back glass, looks awesome!
