"The magic button of nostalgia"

I want to make a “Magic button of nostalgia”. It is just a flashing button, but I may make it do some more things. What do you think about it, and How can I make it?

What’s that? Never heard that term

Well No one has made it before, so never being heard of that term is good.

Can you explain in detail??

this is soooo rand()

It’s a button, and It changes color randomly.
