For some bizarre reason, I really want to learn how to do letterpress printing. This is an old-school process that requires lots of dirty, heavy, expensive equipment, but creates gorgeously tactile typography and graphics — you're literally "pressing" the inked letters onto the paper, after all.
Geeky designers (and the folks who write about them!) love Legos, and Sam Cox and Justin LaRosa are no exception. Under their Physical Fiction aegis, these two graphic designers have put Lego to yet another wonderfully off-label use by constructing a working letterpress printer out of the bricks.
