I’ve been following the processing framework framework for quite a while now. Processing can best be seen as a DSL to ease the task of programming interactive computer generated images and animations build on top of Java.
Most of the time examples are quite straightforward, but last time I checked a noticed this ‘invention’:
PixelRoller
(–update– I fixed the link, which pointed to the wrong site…)
It is a paint roller that paints pixels, designed as a rapid response printing tool specifically to print digital information such as imagery or text onto a great range of surfaces.
Can’t wait to use a tool like this for decorating my house!
