Garden": Don't want to be / Where geometry Has gone on holiday / At the beach Sanity demands / Creatures with hands Not a million tentacles / On a leech! From Cthulhu's Garden in Cosma Shalizi's Cthulhu songbook. |
Dianne Xu has written the best exposition I've seen of the Classification Theorem for Compact Surface. [classification.ps] [classification.pdf]

Topology Without Tears, by Sydney A. Morris
One of my favourite texts is "Topology via Logic" [Cambridge University Press], by Stephen J Vickers which looks at non-Hausdorf topologies and their applications to computer science (well, logic in general). Another paper by the same author also related to computer science is Geometric Logic in Computer Science
