// we are ignoring how "fuck yeah" is ignored in karl's life.

// against each other to repeatedly figure out how to move, so fast, so constant.
// when we have crucial information we need it
// when we find wonderful information we lunge for it
	// we are working with a computer.
	// computers already have a harsh rhythm that goes like a hummingbird's
	// wings and never stops.
	// they need to slow down.
// it ounds like it is true for the cmputer too
// like the molecules of water, its parts buzz, constantly.  but we can have it
// still behave slow and caring.  this buzzing seems important, and we will
// likely need to be able to buzz too, on a larger scale.
// 	we are workin with a rhythm learning pattern here
// 	it cannot buzz, it would err
// 	it cannot wait forever, it would never join the dance
// 	the key is not the silence but the start and end
// 		it would be good to get 'fuck yeah!' from somebody who actually
