i always thought kasperg's (and others) maps were way better than rimroks (whose maps i never understood why anyone liked) blocky maps. i think some people must have confused making cool screens with making cool maps. and the reflective floor trick is nothing new, and it's far from being rimrock's creation. there are tuts everywhere for it.
let him think he's some great mapper... one day he'll realize he's just an advanced noob. good riddance...
