Ok, this is too epic to keep putting off! I'm hereby precommitting to a maniac weekend starting tomorrow! I'll reply here with a link to the time-lapse on Monday...
A more reasonable definition might be "5pm Friday till whenever you go to sleep Sunday night" but this is not about being reasonable (quite the opposite). I have no particular attachment to my sleep schedule so I'm hoping I'll be on a roll Sunday night and push straight through to 9am Monday and then collapse.
