 I don't quite understand the effect. If you have N lights that change state every 1/4 seconds, and the delay between two lights is also 1/4 seconds, then you have only two patterns 1010101010 and 0101010101 .
 Anyway, you can count the number of patterns you want to have, make an object for each (including the 90 lights) and do a pfSequence.

Happy New Year
