Why do stripy shirts make images, shown on television, go flashy and/or blurry?
Apparently this only happens when people wear horizontally striped shirts.
And i think also when the shirts are polka dotted.
How is that happening?
A second, related, question if i may:
Why do laptops – and/or computer screens that we see on television (usually in live transmissions, i think) appear to have rolling, horizontal blue beams.
How is that happening?
