This notion reminds me of my "ceiling pigeons" motif, of when I left the door open, and left to camp out, for court, at my old Section 8 apartment off of Broadway (the original iPigeon.institute slight home exhibition).

The ceiling in my bathroom had caved in and crumbled, due to significant dampness that had built up, undoubtedly from some transient who had occupied my place for a good time, in the bathroom. I could see the rafters, and there were pigeon-ish crumbles and pigeon icon "bamms" of the drywall pieces, and I spotted some nuclear echo pigeon interlopers, up there, in the ceiling, peeking down at me. I caught it on video, as well, but this is the line art ink brush version. |
Pigeonite is a mineral in the clinopyroxene subgroup of the pyroxene group. It has a general formula of (Ca,Mg,Fe)(Mg,Fe)Si2O6. The calcium cation fraction can vary from 5% to 25%, with iron and magnesium making up the rest of the cations.
