The Kindle e-reader device is equipped with an impressive, high resolution e-ink display -which when ‘on’ uses almost no energy.
Today’s invention is a service based on reusing this technology.
Artists could upload digital versions of eg their pencil drawings. These would then be available to Kindle owners as screensavers, for a small fee.
The Kindle is thin and light enough to be slotted into a purpose-designed frame (also available from the big A). Drawings could thus be displayed as domestic adornments when the reader was not otherwise in use.
