Lisp software renderer

My pet Lisp project has been languishing on my laptop recently; I've had a fiddle with the Linux Framebuffer Device interface, and it's occured to me I might more usefully bind to that than the PTC library. Potentially it could be a non X based graphical backend to the McCLIM. Someone is already working on an Open GL backend and that code could map over quite nicely...the fonts would be some kind of awful hack, though...
