Seems to be a dumb (random, possibly?) category-based item browser with keyboard controls and a unique UI. I wouldn't consider this a discovery tool as it doesn't seem to have the intelligence of other systems:
1. Learn what you like and suggest similar things (Pandora, Frank and Oak, Trunk Club)
2. Offer related things regardless of like (Amazon)
3. Allow you to follow people you like and see their latest creations or likes (Pinterest, Instagram)
4. See overall popular content (Pinterest, Instagram)
Some of these would be easier to integrate than others, may be in scope of the project
