digitallineart currently draws from 700+ forms. Every work on the wall comes from one of them: a rule for placing shapes, followed by chance in their number, position, size and colour. Here are all of them, grouped, each with its newest work still on view — 4,979 works hang on the wall right now. Each one stays for 30 days, then it leaves for good.
