Puzzle: 'Pillars'

[Rene]

Those solutions to Amplitude are pretty neat.

Can anyone think of one that actually uses all four streams, though?

I set out to use all four streams, and no packers/un-packers. Did not think it was possible at first, but voila:

    negyfif

Turned out to be almost symetrical as well.

Nice solution Rene.
I should have used separate pathways as well, but I thought the synchronized dozers would be cool.
