The European premiere of Yvette Mattern's stunning laser rainbow projection, "From One To Many", traversed Berlin's night sky from 2.-7. February 2010 and Toulouse' from 11.-16. October 2010.
"Everything, always, collectively, had been moving toward that purified shape latent in the sky"
Thomas Pynchon, Gravity's Rainbow (1973)
The spectacular use of our latest high specification laser technology is particularly apt this year, the 50th anniversary of the invention of the laser.

Technical background information:
Only our world best laser systems are being in use for this outstanding project, developed and modified by our enthusiastic technicians.
Divergence from all beams are below 0,3mrad and maximum of 3mm beam-diameter for the green line, and below 2mm for all other colors. No extra collimating optics are used to keep the rainbow looking more real with slightly overlapping colors after 6km distance.
