As far as video game art and crafts go, I think wood is a totally under represented medium. The few pieces I do see tend to be heavily painted and don't allow the natural beauty of the wood to show through. Thankfully Aristomatic
has got me covered.
These textured SMB1 magnets are made birch wood and man do they look good. I guess you could stain these if you wanted, but why bother? The wood grain and coloring looks great on it's own.
