Bamboo plywood has many redeeming qualities; It's cheap, strong, looks good, and cuts really well. But it's literally impossible to sand, so painting it can be tricky.
If you just blow a bit of paint over the untouched wood you get quite visible grain. This can be used to good effect, and in flat black it tends to look like burnt wood. It helps that the pieces are all cut with respect to the visible grain, with the top panels having vertical grain and the side pieces horizontal.
