Just going through some rock samples for a lab tomorrow (yes, Saturday, Adult Ed class) and thought I'd dig out some unusual ones for the wow factor. For RockExchange 2021 @kleinergeologe.bsky.social sent me a wonderful selection, with detailed notes, that still make me go WOW! Thanks again!

I'm starting to 'collect' screenshots of AI rubbish for illustration of the unreliability of it (I'm being kind!). This is another one to add.
A cautionary note to science students and users of AI.
Always include a scale in your photos. AI attributes the pawprint (no scale) to a cayote, cougar, or bobcat. AI recognises the #derbyuni scale card and the print of a bobcat. No, they belong to feline domesticus aka Bear (a resident of Derby).

This is a brilliant Christmas idea – order three of these wonderful prints and send them to 3 of your enemies. Two of them will lie awake at night wondering what's going on, and one of them will be dead. Wins all round, eh!
Can't figure out if the slump in Christmas sales this year is a result of not using Twitter on principle, the general economic climate, or fact I accidentally revealed that I've stuffed a small amount of poison into one in every three orders to reap victims for the Old Gods

Buy her wonderful art built on skill and wit, or she may haunt you and lay baited traps under a full moon in the depths of Kerry, and then you’ll have to pay anyway to escape
Turns out a combination of not using That Other Site and the economic landscape at the moment in general does, in fact, makes fulfilling the whole "starving artist" stereotype a whole lot more achievable 😅
First year selling my art at Christmas without the Other site, where most of my sales came from, as well as losing US orders to new tariffs, so it'll be a tough one - I put huge work into every order, so even if you can't buy, shares help get them in front of eyes. GRMA! www.ciaraioch.com/artprints

Not doing Black Friday because I'm against the creeping Americanisation of Irish life and can't afford to as a small artist, but WILL be doing Vengeful Hag Friday where for every piece of art you purchase from www.ciaraioch.com/artprints I will fervently wish bad cess to your enemies

These dark patches on the limestone are ancient animal (shrimp-like creatures, we think!) burrows, made when this was a muddy sea floor. It is believed that a storm washed the the animals from these burrows and filled them in with gravel or sand (in this case Crinoid segments).

What a great list of advice. Breithlá Sona duit, a Dharach!
Today is my birthday. 48. Is that old? Well, it's the oldest I've ever been.
Have I learnt anything worth sharing in that time? Let's see.
