Wow, this is the first time I've ever seen it down in 4 years. I thought I had the picture saved.... but I can't pull the full thing off of my 3DS, as the playback is slightly corrupted at the end. Man this is lame :\
EDIT: From the creator of the app on facebook:
"Jens Andersson: Hmm. The colorslive.com server running on Amazon EC2 doesn't want to start. We're working on trying to fix that."
EDIT EDIT: From the creator again:
"Amazon has issued the following status update: "We are currently experiencing delays launching new instances.". colorslive.com is not the only site affected."
So blame amazon I suppose.
FINAL EDIT:
Server back up, check it out.
