After looking back over some of dburka's screencaps on Dribbble... I noticed something different about this one: dribbble.com/shots/87772-Si...
Sure, that's a lot of quarters, but something different than that. Oh yeah! Night time?! I presume.
That was taken in early December... a while ago. But, well, it gives us hope that there will be a day/night cycle in Groddle some day... I guess? Hmm.
PS. Can us alpha testers has one of these business cards each? Pwease? dribbble.com/shots/73262-Gl... :D
