Where the number goes.
D20DAO delivers a random number with a proof attached. This page collects what gets built on it: applications and games, ours and other people's, each one linked to the requests it made and the evidence anyone can replay.
The die is not a placeholder. It is the same die as the one on the home page, drawn a few hundred pixels wide and reduced to five colours from our palette.
