I'm running grooverom5 with HTCHOME2, which is the closest I've gotten to the old HTC Home today screen. There is also a version of HHC that runs with vga, but HTCHOME2 seems to run the cleanest, although the graphics aren't as sharp, but with my eyes, it doesn't really matter. Here are the two threads that I've found that include the best HTC home today screen options. It seems I'm the only one in the diamond forum that feels this way, the TP forum is much more active on this subject.
again, I've had the best luck with HTCHOME2 from this thread.

this one has HHC support, but I have problems with screen rotation, search for my questions about this.

I used to use BigHTChome, it's graphics were better, but it had the rotate problem as well.
