If you want a Curiosity rover of your own but don't quite have NASA's budget, you can save yourself $2,499,999,850 by going with designer Arnold Patrick Martin's beautiful wooden model. It doesn't move, the cameras don't work, and it probably won't survive a trip to Mars, but it's also only $150.
And believe it or not, in a time when manufacturing is made so much easier with 3D printers and laser cutters, Martin actually hand cuts all 120 pieces of this model with a scroll saw. So if you were wondering why it's $150, there's your answer. [Etsy via Technabob]
