Yes, these Gravis Soundcheck flip flops are supposed to look like acoustic foam. Shame they're not actually made of old egg boxes, with a chap from Sound on Sound explaining why they don't really work.
I couldn't find a picture, but Paul Smith make a business suit with a mixing desk printed all over the lining - the same print used on this bag. Got any even lamer clothing inspired by studio gear? (Eventide t-shirts not included...)
