Just a general colour splash would look a whole bunch nicer than the black and white boxes. Just a splash of colour to the b/g would be an improvement tbh, nothing overly fancy - just something that makes it look like it was create in the early 2000's. Other than colour, maybe just restructure it sightly to make it more easy to read and decipher the box thing doesn't do the arcade justice of what it's capable of.
Just personal opinion, don't know what look or feel you guys were going for, or how easy it would be to implement without f'ing up the whole structure to it, but yeh... hey ho...
