The planet Jupiter has always been interesting to me. I think it's astounding that the Great Red Spot is basically a planet-sized storm system.

The Great Red Spot is pretty cool.

Has anyone heard of the the new red spot? A mark on the heavens! Surely, a sign to us that the anti-Christ has been born! ...jk
More on the subject of the Great Red Spot, here's an animated gif I found of Jupiter's storms in action:

I wonder what causes them to have that pattern.

If you mean the different swirling bands of clouds, then it is caused by a combination of gasses (Hydrogen and Helium among other things) that are raging around Jupiter, due in part to the planets very short rotational period of 9 hours 55min, give or take 5 min for the differential rotation. These different bands are also divisions of tropical regional flow against the prevailing winds.

Thats nothing man, did you know its electromagnetic field is so large that, if viewed from earth, would be three times the size of the moon? Awsome Jupiter is...

I wonder if that created any problems for the Galileo mission?

You know, Jupiter's magnetic field is supposed to be one of the causes of Io's volcanism (though the tidal forces are supposed to be a greater factor).

I only knew about the tidal forces. The tidal forces of a black hole would cause "spaghettification" (a real word) because of the massive difference when you get right close.

Impressive!

Sort of in the same vein: visual demonstration of vibrational modes of a metal plate, using sand. WARNING: Turn your speakers down or off, if you want to keep your sanity and sense of hearing! :)

Sure as shit looks like metal crystals to me. I thought early on that I wanted to be a metallurgist, but didn't want to move to cold country.
