Im jealous I didn’t think of these things before Kyouei Ltd. released them as a product. A DVD that fills your TV with solid colors to illuminate the room. A CD with 99 tracks for 99 tones: “When using the ‘random’ function, the CD will automatically select random tones, and make a new melody.” A combination of battery, LED, and balloon that results in a glowing glob of latex.
The only thing cooler than these is a little book titled Count Sheep that was filled with pages of identical sheep arranged in rows and columns, ready for counting.
