I dont understand how you can spend 4 years at a university and not be able to come up with an idea, and then not have a clue know how to implement it, and THEN take the chance of getting an answer by someone like mistakeca.
How about building something that will find buried WMD in your backyard?
EDIT by mechie ... hyedenny, this is supposed to be funny ?
Do not tar everyone with the same brush (or should that read 'Bush') - I don't recall the Americans finding any evidence of WMD, even in the correct country! (or did they search in Syria by mistake?)
