I've blogged about them in the past, so will keep this short and sweet...
In fashion time (much like dog years, only chicer), their autumn winter 2010 show was decades ago, I realise that, but you should still check out this video from it. Viktor and Rolf themselves undress and dress the models centre stage while they show off their newest collection. GENIUS.
They always take 'fashion show' to the absolute limit. That's why they are so ahead of the game.
Amaze.
