I'll be the first one to admit I have an odd fascination with Menger sponges but I'm not the only one. I've collected a few more beautiful spongy creatations from around the web—plus one of my own—in what I hope becomes a regular series of posts on artists and their sponges.
I stumbled across Peter Miller's animated sponge a few days ago and was amazed at the simple beauty of a cube growing into a mind-blowing level nine sponge. His animation is 14-minutes long and is possibly the only animation out there of a sponge of that complexity. His page on sponges has a few other goodies including how to optimize sponges for 3D graphics.
Bathsheba Grossman, an exceedingly talented sculptor, made a metal level four sponge. It's small enough to fit in two hands and would look great anywhere. I would get one immediately but unfortunately, they're no longer for sale due to production difficulties. Cutting all those holes must be pretty difficult so it's understandable. Bathsheba creates many other amazing works of art—many available for sale.
Jeff, a Mengermania reader, sent me his rendering of a level four sponge comprising 336,384 polygons. It took its toll on his computer during the rendering process but it came out great. He's working on building his own level three sponge and I wish him the best of luck.
Since May, when I wrote the post about making sponges out of Post-its, I've been slowly creating a level two sponge out of Post-its at work. I was only able to create a few cubes a day during my limited free time but it turned out great. It's just over six inches square and was made from 864 Post-its. Two photos of it are in the gallery.
I'm always on the lookout for more Menger sponge art, so if you've created something, let me know in the comments below or send me a note.
