Everybody’s got to have something to do in the office during the downtime. Whether you’re waiting for a build, rebooting your machine or just avoiding eyestrain after 4 hours staring at code.

Somehow, I ended up using my downtime to fold up old business cards to build a level 2 Menger Sponge… as inspired by Dr. Jeannine Mosely who explains it better than I can. Unfortunately, my cards are not the right size to contribute to Jeannine’s brave attempt at a level 3 sponge, which she calculates will measure slightly over 54 inches (140 cm) on each side and weigh about 150 pounds (70 kg)!

It’s taking me an awfully long time to do. Getting your hands on 2400 business cards that people no longer want is hard enough, but it turns out that every company in the world seems to have it’s own preferred dimensions for business cards. Definitely a candidate for EU standardisation there…

Here’s some (blurry) photos of my sponge, from conception through to today:

Once it’s finished, maybe it’ll look rather nice with a lamp placed in the middle?
