A few engineer buds of mine went all out on a table. It's made of some nice, quality wood, and was varnished like mad to give it a really nice surface. They used some folding legs from a table on the bottom and made it hinge with some nice brass hinges in the middle for easy storage.
I don't have any pictures of the final product, but here is one from the construction- the two halves were about to be put together at the center with the hinges.
All the holes were jigged and routed out with a nice profile on them.
