A distant cousin of the Yellow Velo?

This is slightly unrelated to the Yellow Velo - but I recently met a distanct cousin of my velo:
The two guys below have built a tandem velomobile out of cedar strips, and are touring across Canada, giving presentations at Elementary schools along the way about global warming. Since I recently also took my velomobile to an elementary school to discuss global warming and alternative transportation, we had an interesting conversation.

I would just like to say - amazing project and good luck to you both!
