"drei treppen ueber der schweiz", i.e. 'three floors on top of switzerland'
i was running 'restromant' in 1999 and 2000.
restromant was intended to be a kind of test array on how to present current art works under rather precisely defined sensual conditions.
"drei treppen ueber der schweiz" is a claim, developed by githo, who belonged to restromant's somehow most constantly visiting participants or participating visitors...
btw. it's likely that in the nearby future there'll be a documentation on restromant in the web.
