Pi in the Ski

I stumbled upon the name of Daniel Tammet, an autistic savant who holds the European record for reciting pi from memory to 22,514 digits in five hours and nine minutes. As impressed by this as anybody would be I quickly looked him up on Wikipedia, where I found this tidbit:

In his mind, he says, each integer up to 10,000 has its own unique shape, colour, texture and feel.

Fascinating. Of course, you know what OTHER unique distinction each integer has?

It's own, you know...number.

Nice try, Daniel. But I'm still not gonna sleep with you.
