Invisible images

About 10 years ago someone wanted me to bid part of an exhibit using invisible ink (UV light receptive.) They wanted to do a day/night jungle scene.
The technology just was not available.
I guess it is now. This is kinda cool, in a black-light era kind of way. :slight_smile:

Day/Night - different planet - what’s the difference… ha ha

Cool though

That is kinda cool :slight_smile:
