here he is!
Well, I bought Calvin at Home Depot for about two dollars today (February 13) with no tag. His leaves are a silvery green, getting more silver as you go closer to the base of the stem and greener getting farther away.
They seemed to tear off easily, especially the ones at the base. I don't even know if it's fair to call them "leaves"- like with most succulents, they're thickish and juicy. They're more pointy then round, they point at the tip, and they're widest part is right after the tip.
The most interesting part of this plant is that he seems to have a droopy stem with a dead bud of a flower at the end. The petals inside are a very pale yellow, and dry - they all fell out when I tried to open the bud.
It has the standard shape, fatter at the bottom and smaller with wider spaced leaves at the top. I don't have a ruler so I can't be exact with measurements but I'd say it's about three inches high and five wide.
