mckinley: Sorry mckinley but you're wrong on that point. The sticky notepad was an new twist on an existing idea. A piece of paper to write notes on is NOT new. It's been around for hundreds of years. People would tear off paper and tape them to surfaces so they wouldn't lose the note. So the basic concept has been around long before any of us was born. We write a note on paper and place it on a bulletin board. Same idea. So your examples fails as an original thought. The inventor built on an existing idea. To be "original" it must be completely new and not copied or derived from something else. Even Jules is WRONG with his example. Puzzles have been around for years and the best you can say about Rubic is he had an unique idea that differed from other manipulating puzzles. The rubic cube comes close but it is still built and influenced by the ideas that preceded it. The Rubic's cube is simply a 3-d model that is manipulated. Such manipulations of 3-d forms have been around since the birth of geometry. Since the rubic cube build on previous known concepts, it's not completely new. Jules will likely disagree and perhaps so will you but you'll both be wrong if you do.
