Portable Ramp at the Piers

I spotted this portable ramp on the Embarcadero while touring the new Exploratorium buildings at Piers 15/17 recently. I don’t have much to say about the thing really, but just wanted to note its ‘understated gracefulness’ as a sculptural object (ha!), especially when it’s not being used to attach anything to the pier. There is something sort of poetic about disembodied stair structures like ladders, single-flight stairs on casters (for boarding planes), step stools, etc. and the way that they can serve as open invitations to connect objects, spaces and places.
