Oh, it's not going to bend at all really. It's not done yet, I need to snazz it up a bit, but yeah, it'll be way minimal by arcade logo standards.

As far as the half sphere, think of those paperweights with stuff inside them. The half sphere will be a solid resin cast, and the logo gets pasted on the bottom, and then gets mounted so that the logo shows through the curved/convex side. As far as paper to print on, I think maybe a translucent sheet will do, I used one for a poem I printed for my first anniversary, and used it to overlay some parchment backing. It came out pretty nice, and when I had held it to a light it let alot through.
