    What if I use an awesome font like Comic Sans and round the faces like party balloons? Still visible?

      It’s all about the size. You can’t use an optical microscope to look at details smaller than the wavelength of visible light. You need an electron microscope for that. Similarly, a wifi camera can’t see details smaller that the wavelength.

      If you made a camera that can see in 100 MHz radio waves, you could probably see mountains, rivers and houses, but anything smaller than 3 m would be nothing but blur.
