Using the same engine as for Proximity/Repulsion, I created this one when experimenting with something that was supposed to become a floor projection for dance-theatre. The glowing response to movements reminded me of bioluminescent plankton, which flashes up when disturbed.
This one ran quite successfully in a number of nightclubs and festivals, including Sisiphos, Wilde Renate, Kater Holzig and the Fusion Festival.
The immediate response to movements works very well when people just walk through the projection and gives enough stimulation to attract people with short attention spans. What I like about it is that although it is based on a relatively simple smoothed particle hydrodynamics style model, it gives nice variety of feedbacks to different movements.
