Picture this...

Not sure if I am the only one who did not know about these until yesterday (apparently the USPS has had them since June).

Made with "thermochromic" ink that reacts at 84.2 degrees F - easily achieved by pressing your finger on them (see here).

I don't know if anyone has posted any graphic art yet but it's a "picture" I guess, so here's what I did over my long lunch break (slow day at work).
It's a desktop background for my new CNC computer.

That's very nice. I did some computer generated art work too and it's amazing what can come out of it.
A long time ago i just generated some blocks of white color on a black background. It came out looking like a night view of a city like New York City where the white blocks looked like lit up windows in the buildings.
Cant remember the program now but it's not too complicated.

I believed they were buried in my defunct personal PC but the backup was there.

After inspecting the holds in a bulk carrier, at the anchor in the access channel to Bahía Blanca, , we saw this front coming from South.

We were urged to leave immediately but it was clear that we would not make it before having it above us.

After that, strong wind and rain precluded any further meaningful pictures. Even our boat went aground for maybe 20 minutes. When we reached the pier, weather was calm, dry and colder. Usual thing for this phenomenon (pampero in the local jargon).
