OK, so my crappy example doesn’t exactly show it in the best light but BlockCAD is a great Freeware Lego modelling tool that has loads of different blocks for you to arrange however you see fit and then render out pictures. Everyone loves Lego and I can see this becoming my latest waste of time. (This is very true – I’m supposed to be working on something less frivolous even as I type this). The best part is that you’re spared the pain that occurs whenever you step on a Lego block in bare feet. Nice.
BlockCAD is Windows only, but Mac users can try Bricksmith, which is apparantly very similar.
