I vote for an ebook reader to be developed which has some sort of bioluminescent backlight. Thus, little bookworms built into the device would make the screen glow with their specially dna-engineered glowing tails. You could even choose which colour you would like. Boy bookworms would give a nice blue backlight, whilst girl bookworms would give a pretty pink backlight. However, I'm not quite sure if bookworms are hemaphrodites so this, ultimately, may prove a serious drawback in the colour choices. Oh well, back to the drawing board.
