in england you can get something called economoy 7, where your electric costs about a third per unit
(so my normal units are just over 16pence, but between midnight and 7am it's only 5.6 or so pence per unit)
therefore, being nocturnal, i'm awake and using my computer at night when electric is cheaper (using computer = not willing to sit with p95 running)
and when i'm sleeping is during the day, where the electric costs 3 times more than my normal (nighttime cheaper) rate
woo for nocturnality
but i'll stop derailing now :P
oh and i love how the spambot 2 posts up stole my post without even quoting me
