March 15th was a clear night here, and the moon happened to be a half moon. I've long wanted to try shooting an "HDR" style photo of the moon with both the illuminated and dark halves visible, so I put the camera on a tripod and gave it a shot. I'll make a separate post with the full-size moon image.
Aside from that, I went on a few bird walks this past month but only took these few keeper photos.

The above hashes-<date>.txt
file contains SHA-256 hashes of all the photos
from this shoot. The hashes-<date>.txt.sig
is a signature of that hashes
file, created with my PGP key. The signature file
itself was written to both the Bitcoin Cash and Algorand blockchains, in the
OP RETURN
and Note
fields respectively, using the transactions below.
In short, this proves that these photos and the signature both existed at the time the
transactions were written to the Bitcoin Cash and Algorand blockchains.
This blog post has more details.
