Dancing paint

I have been looking at photos with dancing paint for years and years and years. Bought the speakers and paint last year. Had to shoot a photo to demonstrate 'sound' and decided it is time.

Brilliant photos and tips here.

My, totally unsuccessful, attempts here:

Will I do it again? Never ever :(
Looking at it again I can see that I focused on the drops on the other side instead of the moving paint. When you look at successful dancing paint photos you don't have an idea how small it actually is - it is only when you do it that you realise you have to go in sooooo close and wipe paint off the lens every now and then. And I didn't use a tripod as I had the whole setup on the floor, should have put the camera on a book or something, instead of holding it.
