Make a shape
Add words and place them on a 40 by 40 grid. A word's position and size are the poem: a column of short words is a column, a long word across the middle is a line. Save it and you get a link. It stays private until you choose to send it to the gallery, and a person reviews it before anyone else can see it.
Click a word, or pick it from the list, then move it with the arrow keys or the buttons. Click an empty cell to put the chosen word there. Words may overlap. Cells run from 1 to 40 across and down.
