Have a look at this 35 RGB LEDs Video .... to see a shirt pocket Heart changing Red hue in Step 2: on a 9V Battery and a PIC Stamp.
Failing that go here try this URL
It is worth seeing.
Oah crap I got to do this again something messed up the first time I tried to say this.
Yes it can be done in a number of different ways.
The first way, you can use a pic ( Programmable IC).
The second way you can build a 555 timer.
To drive a up down counter.
To drive a digital pot.
To drive a LED driver.
It is simple to do and hard to describe but it is not that hard to do if you can read a schematic.
Put them in series strings of six LEDs with a 100 Ohm resistor on each string.
Connect that to a 100 Ohm 0.25W pot.
