not strobe lights, theyre kinda like wire or string.

Answer 1

My friend is a DJ and uses these special lighting techniques whenever he does a gig.....he usually gets his equipment at Spencers gifts, and other local specialty shops.  

This one shows circles of color:

Then you have your old fashioned reflective disco ball:

Lasers/LED are powerful and can shine a light a much further distance:
