They're the work of Judson Beaumont -- the gentleman pictured here, I'm guessing -- and his Vancouver-based company, named (probably ironically) Straight Line Designs, which creates children's furniture (and custom one-of-a-kind pieces and projects for children's hospitals, etc.).
Ominously, there's no mention of prices on the site. If you have to ask, you probably
can't afford it.
Bad table! (Hey, that's what it's called.)
