Tetrascii 1

What do we get when you cross two old computer phenomena: ASCII and Tetris?

Tetrascii

The "rules" are as follows:

1. Each glyph must fit within a 10x10 grid.
2. The foreground pixels must be constructible from standard tetrominoes.
3. The background pixels (including counters) must be constructible from standard tetrominoes.

It's surprisingly difficult to construct a readable font. Obviously, I've cheated with the lowercase letters; but in my defence, the counters of the uppercase letters are hard enough. The minimum counter size is four pixels and you can see the trouble I had with the dollar sign.

A project for another time would be to animate the construction of text by falling pieces.
