You draw 100 different pictures to see if you can, from what I've seen of it

never understood it myself lol XD

You open up 100 commission slots, your choice of price or free even -- and o course you can take only a couple at a time if all 100 would be too much.

But it is essentially to try and push yourself and expand your horizons -- take on the challenge of 100 different pictures to see if you are able to do it -- as well as get in quite a good bit o practice. ^_^

The specifics people put in are varied by person to person, of course. For instance, one person I saw was selling them but rather than a person choosing what was drawn they simply give a re and the rest of it (type of picture, perspective, colored or not, etc) was rolled on a series of charts so it was random even for the artist!

It's just a way to challenge yourself, get practice in, and possibly make new friends and watchers ^_^ And profit i you charge XD
