This part seems already working. This code make the trick:

	(30 random eToysLT: 5)
		ifTrue: [self setHeadingTheta: 180 random.
			self setX: 1000 random.
			self setY: 1000 random]
		ifFalse: [self forward: 20]

The fading is now the pending part for the graphical effect. I would
like also to copy this behaviour, but on poster, copies of the same
object with different look (I remember something about siblings)
