Paul is a little strange - he collects empty cans of Pepsi. As far as we can tell, his desire to collect cans is not for any nefarious Krameresque money making scheme in Western Australia, but for the sheer joy of collecting cans, like an anorak of the carbonated drink world.
These empty cans often are the targets of various projectiles which are being hurled around the office, and make for great target practice with the airzooka. So it should come as no surprise that on a quiet Thursday afternoon, some of the more restless members of the bioinformatics team decided to create a monument to the cans around Paul's desk. This page serves as a record of that monument.
The can-monument was quickly destroyed by Paul, using the Airzooka. You can watch a brief movie of the destruction of the tower by performing clicking actions on and around the linky for the movie.
