Painting by Monet - The House Seen From the Rose Garden.
This painting the red and yellow version was painted as seen through his left eye which was limited to the wavelengths allowed by his cataract.The clouded lenses prevented him from seeing anything but reds and yellows.
The painting in deep blue and violet (the one originally posted) is assumed to have been Monet's color interpretation with his right eye, the lens of which had been completely removed, a condition called aphakia. Through this lens-less eye, Monet could see deep into the blue spectrum, and perhaps into the ultraviolet range, which is usually obscured by the lens of the normal eye.

These (laminar jets) are really cheap and easy to build. Hackaday video with an overview. They're really only a bit of PVC, a sponge, some screen material and drinking straws.
Edward de Vere was nine when the Midsummer Night's Dream was written. So, basically implausible bullshit.
