Fun with plywood from a dumpster

Here is something fun and new.
I found a plywood section of an old pallet in the dumpster at Home Depo.
I have used it in a number of experiments.
this one came out kinda nice.
Wavy gravy plywood with cherry and walnut with mahogany bottom and top.
Gives me other better ideas on how to combine this technique with other venues.
