Haloasis is an interesting device that uses a rapidly spinning LED bar to produce a constantly changing display inside a clear plastic tube. It seems geared towards creatively displaying lyrics from your music. It’s not even in kickstarter yet, but it’ll be interesting to see how they do. I’m curious how loud it is, because these devices are never exactly quiet due to the high RPM spinning LED bars.

I think it could be more cool as a display for interesting information since my karaoke skills are less than amazing.
