So the name alone makes me want to love this thing, but the whole project is v. cool.
This is the Rubikon Pinhole Rebel, a pdf kit you can download and print off in order to create a pin hole camera. I remember trying out pin hole cameras in science class many moons ago and it was incredibly satisfying. Look at the style of image you can produce, what's not to love.
Adding this one to my 'what to do with boys on the school holidays' survival kit.
Head over to here for the download and some history.
