Looks like this is coming along nicely. Hopefully I'll have time to make it out to Makers Fair and see it in person.
It's hard to tell from pictures, what are the bubbles? Spots where the acetone was dripped onto the sanded ABS and not immediately removed?
Any plans to integrate some type of interactive screen? It'd be really cool to splice in an old smart phone with a Pip-boy themed interface or something similar.
