Mult led controle circuit

I will be using a picaxe 08M for the controller.

OUTPUT #1: this output will have to have a digital potentiometer as R1 or R2 in a 555IC timer circuit that produces square waves Flickering 8 LED's. The variable resistance will change the flash rate, making the LED's filcker randomly. I would like a slow and steady flicker, not rapid.

OUTPUT #2: this output will have to use an RGB LED to produce all sorts of randome colors.

OUTPUT #3: this output will have to control 6 LED's doing the same thing as output 1, but they will both be different rates because of the different randome numbers selected by the chip.

OUTPUT #4: this output will have the assistence of input one (in whatever way anyone can come up with) to rail and lower a small object on some yarn about 6 inches.

and all of the other values are pretty much up in the air. I ned help to designe the schematic. Thanks guys

How do you imagine eight LEDs to flicker randomly if connected to one single output?

they will be the same, but it will do the job right, only 6 others need to be different (see OUTPUT #3). If you are refering to the draw of too many mA, I assume I'll use transistors.
