I'm sure just about everybody has seen the pyspades day/night cycle by now, but for anyone who hasn't I recorded and uploaded a quick video in fraps showing a bit of it in action. See what you think.

Of course, it was only after I uploaded it that I found there were already quite a few daycycle videos up, however I didn't see any others that showed it happening in real time during a firefight, so there you go. Have fun with it.
