there is an article in popular science about this pretty eccentric scientist that spent 11 years working on making colored bubbles.
it is a decent read and can be found
here (pop sci)
a company that is going to likely make a bunch of money from these things has the product Zubbles, which has pictures and video on their website
here (zubbles).
i had never considered colored bubbles, but these things look pretty sweet. as far as bubbles go.
