I was thinking (big original mistake, I know),
instead of turning the hourglass upside down, like the Wait... cursor I've been watching for the last 10 minutes does, why don't we use a Klein Bottle as hourglass?

this way... as in that bottle there is only one space and not two separated regions.... when all the sand flows outside... it will engulf the whole universe...

sounds right
It doesn't appear to be an original thought tho...

I was thinking it would be much more than an hour glass!
