When you participate and get a frame, you own it. You own the block that is encapsulated within. The abstract Pollock-esque wall serves as a base layer, kind of like the bedrock and soil of earth where we populate and grow. You can simply just frame it and name its beauty from the natural state. Or you can add on the base layer by painting it over, paint integration and paint transformation. 

Because you own that frame block, you are free to also include other mixed media like polaroids, stickers, trinkets, collectibles and even advertisements. The physical limitation is the frame dimension, but the creative limitations is unbounded. Show us what you are.
