drag to expand text area, press backspace to activate, type any valid expression in the first line to add it to the bottom, use semi colons in the first line to seperate expression

u/username

while editing, you should have an invalid expression to have the cursor stay in the first line
u/username

e.g. copy this into the first line d=7;d*c;d!=c;d=c;d!=c

American flag. Initialy I attempted it with a blue rectangle on top of which I added white rectangles for the stars, but I couldn't get it short enough. This looks way worse, but it's also way shorter. Would be curious to see if anyone can get a better looking US flag in this space.

Small change to use separate random values for X and Y axis, greatly increases the variety of designs that can be created.
