Many Ways Wavy Lines 2

Photoshop is almost like some sort of infinite void where tools + objects = a choice of results that are all different or the same for something you want to do, or didn't know you could do but do know now.

Lol.

Oh yeah almost forgot to narrate this - these were one dimensional waves, just a wavy lines stacked on top of each other, then I used a tool which some how added like a shadow under each wavy line. Took a bit of play (right) but ended up with a smooth graduated look, under each wave.
