Measuring font ink-use by hand-drawing sample text with ball-point pens

Clever work by Matt Robinson and Tom Wrigglesworth: they drew the same piece of sample text in several fonts at large scale using transparent Bic pens, then measured the remaining ink in the barrels to show the comparative consumption used by each face. Yes, you could probably write some code that calculated the area used by the faces described in their PostScript files, but where would the fun be in that?
