Alright, let's see what you can come up with here. What are the greatest things ever invented? It doesn't have to be anything big, nothing important...just something you think is worth it's weight in gold, or think is just a supperior product. Here's my list: Crayons - what more needs to be said? wooden blocks for kids - either shapes or the ones with letters/numbers/pictures on them Nalgene bottles - nearly indestructable LED flashlights Those salt packs you get at fast food places with the two small "tubes" of salt. Pure genius. Digital Cameras - a weak start, but look where they're going... Apple iPod/MP3 files - I don't know how I ever got along without them.
