Not the highest priority item but it'd be very cool if there were an easy way to output high quality cartoon and blueprint styled renders of designs. It'd be great for visualization and marketing, and could be very userul for things like filing design patent applications.
Extreme bonus points if you rendered to a vector format (.svg / .pdf) so the lines and curves end up being infinite resolution 2D projections rather than bitmaps (I have an immediate application for that but I'm sure people will love it).
