I thought that only a video won't be enough, so here is a demo!

And a video for those who are too lazy
(this took some time, any advices on how to convert video (lower it's size) after capturing with fraps is welcome):
fps prototype #1

Shaders aren't enabled yet, not really needed at this point.
If any bugs found, please report (there are two bugs in the video, already fixed in the demo).

Greets!
