Hey, don't knock it. I bought my son the Blisslights Sky Galaxy for Christmas at the amazing low price of $42... blue nebula and blue stars. It's brighter and has more features than the "pro" Blisslight with green stars that I bought for $400+ many years ago (and no longer have, because someone stole it from an event).
"Dancing Under The Stars" might have been a silly add-on in retrospect, but some couples wanted and LOVED it.
