No matter where we walked in [the touristy part of] San Antonio, an orange squiggle followed us, always just catching the corner of the eye. It is La Antorcha de la Amistad,and it makes me think of a 3D-printed puzzle or unusual key. Maybe to a geometer's lair?
The color gradients across the sky and the sculpture were very appealing to me.I'm not sure how the lock would work, exactly --- maybe you put the key in, turn slightly, move again in the z axis, turn again, then shimmy in a move given by a simple equation in polar coordinates?
Maybe it's the extrusion of some more complicated being into our space, and the intruder is trying to be polite and not move in the hopes that no one will notice.
This post's theme word is bidentate, "having two teeth or toothlike parts." Thank goodness the tentacle was only bidentate.
