Last night, I had a #weirdDream about a new product announced at NAMM, called the Absorbian. It was basically this dense, compact cube that had two handles you pulled apart, and it expanded into about a 8x8x8 block that completely absorbed any sound around it. Perfect for recording clean vocals in a busy industrial wearhouse, but small enough when folded that you could easily carry it in a purse. It was hollow in the middle, so you put whatever you wanted isolated inside the cube once expanded.
