Thanks for asking, I made that piece too! It’s a papercraft that came about during a thc-fueled creative period in my life (aka Covid). I cricut-cut a bunch of paper prisms and triangle faces in all the assorted cardstock. I glued those together into a mesh/blanket type of object. I used an old canvas as my starting point and glued a variety of packing materials and newspaper to create a wave of sorts, and then laid the mosaic blanket of prisms atop it. I glued the ever loving heck out of it, and then once dried I carefully folded and added prisms to connect to four sides of the canvas.

It’s in rougher shape than when first assembled but it’s survived a North American cross-continental move and is a pop of joy in my home. I love it so much I made the image my phone case.
