Well, indeed, this lens is a very special beast: This SHROOM/LSD-effect I used happens when slightly defocussed. Certabily not a lens for every day, but used at the right moment, no other I know could produce such images!!
Nope, there will be no others: in 2012 I was able to acquire three remaining prototypes of those lenses, made 1992, which came from company of the inventor, Richard Nye and his company, Nye Optical of La Mesa CA, when his son liquidated the remains after the passing of his father. I was very excited to find such lenses, but they turned out to be a bit tricky to convert and adapt to digital cameras. Now with mirrorless ones, it looked rather promising... and I finally succeeded this year.
I got one f1.1/90mm Lyman Apha II lenses and two f2.8/200mm Lyman Alpha I lenses, of which I recently sold one. The f2.8/200mm is much more "tamed" than that "wild horse" f1.1/90mm...
The full album of images for the f1.1/90mm is here:

Btw. all those lesnes were once made to record deep UV images, hence their "Lyman Alpha" name, which denotes the Hydrogen 121nm spectral line.
