this is some kind of spaceship or something.
Thanks to this geeky DIY project, your cat can boldly go where no cat has gone before! Make a feline-friendly model of the Enterprise and a Romulan Bird of Prey. Between this and the Companion Cube cat bed project, you can have the nerdiest (and awesomest, by extension) pet accessories ever.
To see how this was built step-by-step, check out the main page over on Instructables.
