Original idea from Fotoopa, I just made a simpler setup.
Take a look at the incredible Fotoopa Water Figures at Pbase, there's setup instructions on his timing systems.
Sorry for the mess, this is my first setup post :)
The idea here is to put water drops to dance!
I put some small drops on my subwoofer with the cone turned up, then sent some bass frequencies from my notebook. I tried 70hz, 110hz and 200hz, the results are very different on each frequency.
The room was dark, the camera set for a long exposure, 1sec was enough. All light is provided by the flash, which is triggred by a sound trigger connected to a Cactus wireless remote (if 430EX had a PC connection I would not need the Cactus in this setup).
Conveniently, the sound trigger is triggered when the subwoofer makes sound :) I had to add a little bit of delay to get the drops jumping, the whole thing is very fast!
Update: I did this again with some changes to the setup... added a colored or reflective plastic on top of the subwoofer, colored background, added another flash head and now I'm using my new Canon EF 100mm f/2.8 Macro lens.
Update 2: See the whole new setup here.
See my High Speed set for more photos with this setup and the sound trigger.

A idéia aqui é colocar gotas d'agua pra dançar!
Coloquei algumas pequenas gotas em meu subwoofer com o cone virado pra cima, daí mandei umas frequencias graves pelo meu notebook. Experimentei com 70hz, 110hz e 200hz, os resultados foram bem diferentes em cada frequencia.
A sala estava escura, a camera configurada para longa exposição, 1seg foi suficiente. Toda a luz vem do flash, que foi acionado por um sound trigger conectado a um Cactus wireless remote (se o 430EX tivesse PC connection eu não precisaria do Cactus nesse setup).
Convenientemente, o sound trigger é ativado quando o subwoofer emite som :) Eu tive que adiconar um pouco de delay para pegar as gotas pulando, a gambiarra toda é muito rápida!
