It's sort of a re-imagined word processor (implemented in Flash). It lets you select an from an array of things to write on (masking tape, back of a phone bill, a lighter, etc.) and what size and level of messiness you want to write with.

Some standard word processing functions are implemented in surprising ways. "Deleting" just scribbles out a word. "Cut" suggests that you print the document first and then cut it up.

Other buttons in the editor window are more playful in nature. A "bored" button suggests that you go outside and play, for example.

It's a parody of a word processor that lets you "handwrite" on scraps of paper and such, with lots of semi-useless buttons like a spell check that tells you to look words up in a dictionary.
