Fritz Haeg and I designed Machine, a space that I'm running in Echo Park. Part of the design uses this really beautiful ploycarbonite material called Polygal for the interior walls. This material is highly unreactive - nothing will stick to it. Because the surface of it is so nice, we were opposed to drilling or bolting it. So we came up with the idea of using these really intense magnets. In the end, we couldn't get the magnets to stick to the polygal either. So I put them up for sale on my website, thinking it would be a joke between me and Fritz and the one or two random friends who occasionally visit markallen.com.
Imagine my surprise when I checked my email this morning and saw that I'd sold 40 magnets. Oops. It was posted to boing boing, which is of course terribly flattering, but since I only have 12 magnets, and I'm selling them basically for what I bought them, and I'm not charging for shipping, I end up losing money.
So, if you're here looking for magnets, you can buy them from All Electronics for $4.75 (plus shipping)
