thank you lewis. i'm pretty sure my friend does not mind me showing off his work
here you go:
lighting is pretty simple: the wallcoverings are white fabric, behind that there is a red lamp, so you see on the inside the gradient.
on the tables we had generic table lamps.
above the bars we had these lamps by foscarini.
above the stage between the green "bars" there should be spots, but we did not want to show them.
also if there would have been some dark sport, then there would have been the possibility to hang them from the ceiling.
due to the timelimit we did not emphasize too much on propper lighting, just lighting for the atmosphere of the room. besides the timelimit, we had other restraints too: we live 200 km apart and we both work full-time. we did this in four weeks, sitting at the same table just twice.
