Invention? I didn't know that was something modern people did these days... unless you're talking about improving machines in engineering or something. Oh wait you're not actually going to make it right? Just brainstorming useless ideas?
Mine wasn't off topic, I gave him an invention that was simple and easy to do, and I legitamitely believe that he should use it, modify it, or at least pay a thought to the concept of it.
A clip that you add to the back of a folding chair to prevent it from collapsing when you sit/stand on it.
A bit of metal you hang off one of the lower rungs of a ladder, then if it slips the metal hits the floor and locks it in place.
Okay, maybe that was a bit conceited, but I do think it is a good idea. That, and the comment I replied to said that EVERY reply to the thread would be off topic.
Maybe you should make speakers for people without the new nano and ipod 2g and above. You can use cups to amplify the headphones sound like a megaphone.
