This has given me an (admittedly grandiose) idea for a large "spiral" light which like the small one would be more for low-level lighting and decorative effect.
Take an RGB or RGB/W LED strip and wrap in spiral around a long cardboard or plastic tube. Two could be wrapped in parallel "bifilar" fashion. USB IR-controlled strips are common and cheap. I can get 6-footer for about $10 at HD (I think Walmart has similar deal). Even a 3-footer is only $4 OTC from a "dollar store" but may not be long enough and I'd skip the bother of trying to connect two in series thought it's possible.
Wire the strip(s) to USB power adapter(s) and hang the thing from a ceiling. Large plastic "bulb" around the whole thing is optional! (on second thought,not advised).
A couple of minor issues come to mind. Cheap strips are good for basic colours plus limited mixes, typically not all great (on these, white is bluish, and yellow is "dirty"). Also, using two strips and trying to control independently could be awkward unless each IR sensor is somehow isolated from the other.
