If there's one thing I can say with confidence, it's that evaporation has taken place. Here's the view of the grow-house. You can see squiggles where the "quick" ink has developed. The gaps are where the "slow" ink was. It didn't develop; presumably it died in transit (or something).
I must, right away, acknowledge both the mould, and the fact that one of the inks did disappear and reappear. It looks like green ink, though; even up close, there's none of the unevenenness you would expect from a grown product. And of course, being wet and November, it grew black mould.
The ink is visible all the way through the paper, but you'd expect that from an ink you had to use on wet paper, and that had sat on agar jelly for ten days, anyway.
Harley got interested and decided to add her pawsworth to my doodlings. You can see the easel behind her - this came in the package. You stood the ink picture in its greenhouse on it for three to ten days for the Living Ink picture to "grow".
My soggy, mouldy, paw-printed magnum opus:
I think we can safely say that this is not a Kickstarter you'll see for sale on Firebox any time soon.
