There is currently an exhibit in Germany at the Museum Sinclair-House, Bad Homburg within the "Wandelmut" (willingness to change) series, which has some of my multispectral works on display. Visible here is a Rudbeckia hirta flower in human vision, simulated bee and butterfly vision, showing the "landing platform" only bees and butterflies can see, as they have the ability to see ultraviolet light (300-400nm), which we humans cannot see.

I have written about that Rudbeckia hirta flower HERE before,
Stay tuned, more will follow on that fascinating subject...
