Singapore's most wanted

The talk of the fly room for the last few days has been who created this great piece of photoshopping and stuck it on the notice board in our lab (next to the original). So after spending several days grilling people, the original artist has come forward. (I just wanted to get a copy to post here...)
Thanks to Gu Ying in Feng Wei's lab for brighting up my week (and nearly getting me arrested).

If none of this makes any sense, here's some help.
