to the prophets... (aand anyone with a good knowledge of london bus routes)

do any of you know if it's physically possible to get from computer blue in shorditch back to whetstone (ie, very north london) via tube/night bus? (can't really afford a cab at the mo). Actually, they're probs going to be on after the last tube, arn't they? I've been studying the night bus routes map on tfl for 20 mins, but can't quite figure out a way...
