Aliens find TV weird

Aliens would likely find TV to be very strange. And I'm not talking about reality shows, either. They might find Computer monitors strange as well. TV's and monitors exploit the fact that our eyes are sensitive to only three colors, and so only produce those three wavelengths (red,green,blue). Unlike the real world, which has a more varied spectrum.

So assuming an alien being would see a continuous spectrum (assuming they see visible light at all), or even that they would see different discrete colors than humans, color CRT tubes would look very strange. The strangest part might be for them to realize that we believe the picture on the TV matches what we see in the real world.

Even our line drawings might look strange. Our brains operate by doing edge detection (among other things) and performing pattern recognition. (suggested activity: start drawing lines on paper until it looks like something recognizable. Repeat until you figure out what lines you have to draw to evoke various images.) Alien brains might not do such processing, so line drawings would not have the same impact to them.
