I make skins and wraps for all kinds of stuff, as soon as I get my spark ill be making some. However, if the top shell is easy to remove then Ill be whipping mine off and giving it a nice paint job.
If people start selling custom painted top covers, I might be interested in that. Would also be interested in seeing what additions they can add via a 3D printed cover.At least from the demo unit breakdown videos and such, the case appears to be far from easy to remove utilizing screws hidden by plastic caps and clips.
