Open source localStorage based mockup tool

A nice little open source app for designing web page mockups and saving
them to an image.

Perhaps could be adapted to use write standards to save your mockups to a
remote data store....

PS I wonder is there a directory of apps that work with localStorage, or
maybe an idea to start a wiki page?
