Boing Boing on a roll

Not that Boing Boing needs pointers from me, but they appear to be on a roll lately. Apart from the post on chaotic crochet, they have a number of posts on mathematical/geometric subjects. How can you resist posts with lines like "Geometry rules" and "When random numbers were cool" ?

Here, for your reading pleasure..

• How to make a desk and chair from one sheet of plywood (the site has been Boinged, but should be back up shortly)
• A description (from 1959) of how to generate physical randomness
• A collection of random numbers from RAND.
