I think this thread is as serious as you want it to be.
In some ways it's great that it exists because it's a pressure valve and there have actually been a couple of good ideas pop up on here which might make fun projects in their own right.
I hope some of the ideas that popped up here get carried over onto less single issue threads for further discussion.
No-one expects anyone to change anyone's mind on these pages but it hasn't been a total waste of time.
