Neon effect

Thanks,

I will try some, but how can I randomize a sequence of lighting according a numbers stored in EEPROM and finally light up all LED-s ?

your table could contain the lighting sequence which you want to produce

example
00011001 - light 3 leds
00100101 - light another 3 leds
11100011 - another pattern

Do this and fill your table with whatever you want.

His projects don't use a PIC, but you might take a look at:

You can make a PIC emulate the twisted ring counter he uses, or do it with random number generation, all without EEPROM tables. If you want some code examples of both approaches, I can send them to you.
