Fujifilm Darkless

Here is yet another cute and innovative do-it-yourself product from the very creative Fujifilm that apparently never made it to the English-speaking world.  Like the Brooks Pixmat, Fujifilm's Darkless developed a roll of 35mm film in the can, with expected irregularities.

But, the fun is not lost on the Japanese author of this link, translated in google translate from Japanese. Or this one (warning, nudity) Why not color?

Anyone have an idea of the date of this product?
