Thought I’d give it a shot this year after having watched Notch (developer of Minecraft) competing in Ludum-Dare for the past 2.792 years (thanks wolfram-alpha!). I usually develop my stuff in Java, Python, C#, (some) C, PHP, Javascript and Go. I’m intending to write this in Java.

Monitors are 2x Samsung B2430 (23″ @ 1920×1080) + 1x Samsung 2333 (23″ @ 1920×1080) + 1x Samsung 931BW (19″ @ 1440×900).
Got a fresh windows install (since yesterday since last reinstall was on Christmas day last year, and it has been bugging out for months..)
Will be developing the project in Eclipse, language will be Java (as mentioned above).
Paint.NET, maybe GIMP for image editing
Was considering using my in-development networking library (will be releasing as open-source, in all the listed languages above in a few weeks) but after considering it, it would probably be useless implementing multi-player.
May try streaming it, but really don’t think I’d get any viewers.

The main issue I’ve got at present is no decent time-lapse software. I’ve tried ChronoLapse but it seems to have been designed for dual-monitor at most, I’m able to get it to display right 3 monitors using the “subsection” settings but the most I can get of left monitor is simply black (using negative coordinates).
Just to let you know I’m “ylt” in IRC, and I voted against kittens despite having “ylt!ylt@nyan.nyan.nyan.nyan.nyan.nyan.nyan.nyan.nyan.nyan.nyan.d3s.co” as my host-mask! 
Wondering, anybody got ideas on compatible time-lapse software? Temporarily fixed it by setting primary monitor to left, moved taskbar to 2nd left screen and then specifying exact coordinates in “subsection” (in ChronoLapse).
