At Burning Man
in 2001, there was a van
made up to look like the Totoro catbus that scampered around the Black Rock desert
The catbus was completely covered in soft fur. It was closely patterned after the "real thing", kitty stripes and all. On the back, outside, the cat had a firm tail that could seat two to three playa people. In the front, it had a big Cheshire cat smile with giant whiskers, red-eyed rats, and bus route label. (e.g. little sister) It had legs, but moved around on well-hidden wheels. The door had been torn off, and covered in fur, so you could hop in at any time, even while it was moving.
The inside of the catbus was also one hundred percent furry, from floor to ceiling. Couch-like fur seats ran along the edges, so everyone would be facing each other. There was seating for about 10-12 people. The inside was very friendly, (did I mention furry?) and played funky electronic music. In case there was any doubt, a little totoro swung from the rear-view mirror. The cat's face slightly blocked the driver's view, but the driver (and creator) claimed the catbus was street-legal, even in the real world.
I was completely surprised to see the roving catbus appear, sometime after midnight. After riding it, though, I must have had a smile as big as the cat's.
