Graffitti Archaeology and the Best Homework Ever

Very cool!... I absent-mindedly doodle those kinds of images all the time (I always thought of them as elaborate ribbons)... I never knew they had a name.

Very, very interesting. Thanks DragonBoy.

Pretty, damn, cool.

Also note his Letter-Color Synaesthesia. (I know that B and 2 are reddish-brown, but that's all.) Also, since Cassidy is a good friend from way back, I can vouch that he has forgotten more small interesting facts (which can be assembled into fascinating points) that you'll ever remember. Or vice versa.

Also: Here he is.

Wow, argybarg, that was incredibly interesting.

Also enjoy the ol' George Dantzig homework story.

I assumed Cassidy was a girl and I was happy, because I dig it when chicks are into mathematics like me. Then I saw his pictures.

All the same, pretty cool stuff. He's a hippie mathematician/artist.

argybarg - thats awesome!

that could lead to awkward situations though....

cassidy: "hey dave"
mike: "its mike"
cassidy: "sorry, you're colored the same as a dave!"
mike: "...."

Nice post, good links! I want a go on the telestereoscope!

I want a go on the telestereoscope!
Me too! What do you see, a magnified, wider depth-of-field, greater peripheral vision, stereoscope? It's not really explained in any of the links.

Here's the telestereoscope faq.

Shall I google anything else for y'all?

Banchoff's student, Cassidy Curtis, went on to do computer animation for XAOS, an advertising agency in San Francisco, where his credits included the countdown visual sequence for MTV.

I found this a bit deflating. No cure for cancer, then?

What? You think MTV isn't working on a cure for cancer?

That guy is my new hero.

Great post DragonBoy and neat story! Cassidy Curtis' beautiful math art reminds me of ribbon candy. His expression generator of mixed emotions is interesting. Enjoyed the alphabets links on his OtherThings site, especially the Hinglish alphabet. His Graffitti Archaeology site is awesome, what a cool idea

Sites he might like: the evolution of the alphabet animation, Color of My Sound, other math art.

Those level sets can be generated by a slightly simpler, more symmetric 3-variable function. If you have a good 3-D grapher - Maple or Mathematica both do fine, and I'm sure a zillion other things would do the job, these days - try taking a look at the level sets of:

The critical levels are nicely placed at 0, 2, 4, and 6. The most interesting level sets occur between 2 and 4, and the most interesting changes in topology occur at 2 and 4. (At 2, there are 6 cones touching at the origin. At 4, there are lots of little cones coming in from the corners along the edges.)

His colours are all wrong. A is red, for example. Looking at other people's letter/colour synasthesia relationships makes me feel really odd--almost queasy.

This, however, was a really really interesting post. Thank you. I got to meet someone brilliant today because of it (speaking in the internet "meet" sense of course).

Here's a quick rendering of the level sets. If I had to produce that by hand, I'd be sunk, even if I knew in advance what the picture was supposed to look like - those hand drawing are amazing, and seriously give me nostalgia for days when textbooks would include hand-drawn diagrams like that. They had character, and the super-precise, neat-and-tidy postscript diagrams we get in every book these days are simultaneously technically impressive and depressingly homogeneous.

"(My friend would never have settled for a tattoo that she knew was topologically equivalent to a disk!)"

How cool is that?

This guy = genius.
Me = envious.

I hope he does some graffiti.

It's finding esoteric gem posts like these that more than justifies occasionally hitting the 'popular favorites' link. Outstanding in at least 3 dimensions. Thanks DragonBoy!

Thanks for all the compliments on this post. I don't understand why there are not more posts like this, it's not hard to use the googles to find additional links supporting what would otherwise be a one link post. In the case of this guy, it was pretty easy to hit on 'best of the web' material because he's doing some pretty amazing stuff.

Still, thanks for the props.

I feel stoopid.
