This is a very good point. Having perfectly synchronized oscillators wouldn't look as nice. I separated the LED strings into two groups, each driven by its own oscillator. The second oscillator produces a slightly lower frequency to ensure proper de-synchronization. This configuration also leaves one NAND gate unused, not sure what to do with it. I might just tie its both inputs to GND.

I'll breadboard this circuit even though in the end it may not be worth to build it.

Are the switch devices in your picture FETs? They do not have any arrow symbols (N-type, P-type) but I suppose they are N-type as their emitters are connected to ground.
Driving the LED strings with FETs might be a nice idea as they would not need a constant base current to turn on. Are there any equivalent FET devices as 2N3904/2N3906 or BC547/BC557?
