I've previously own a colorDMD (STTNG) and I have to say I was not impressed by the panel.
Yes, the color animations are nice but I can't enjoy them.
I have a background as a graphic designer ( www.tonygraf.nu ) and I always calibrate my monitors and I'm very specific when it come to brightness and contrast, the same goes for my home theatre, let me tell you this, the viewing angle and the colorDMD panel is horrible.
With such horrible viewing angle you will never get a completely black background and it's just an eyesore for me, I am unable to enjoy the animations when I can clearly see that they're displayed on a low contras LCD panel.
Until they get better panels colorDMD is out for me. I might consider buying on if it was priced below 50% of the current price.
Sorry for the obvious plug for my website.
