This week’s challenge calls for something intricate, and I immediately thought of this wall at the Exploratorium.This is part of the “Simply Smashing” exhibit by Rebecca Cummins: A 20-foot wall of about 900 glasses, all filled with water to create optical effects with the reflections. Large version available here. Another angle can be seen here.
There are several arches in The Alcazaba. This one near the top of the citadel doubles as a spectacular window.
An awesome window I found at the corner of Geary & Franklin in San Francisco.
If you go exploring on foot in San Francisco, it won’t take long to find some awesome artwork. However, not all of it is in plain sight; this intricate design is hidden on the underside of a balcony somewhere on Russian Hill. The only way you’ll see it is if you’re walking under it and just happen to look up. It pays to keep your eyes open.
