Topic: I found this to be super-cool

Take five minutes to look at this. There are a million "we're so small and the universe is so big" powerpoint type things floating around that we've all seen. But this is a unique interactive presentation that demonstrates the vastness of the universe both large and small (plus the music is soothingly tranquil). Start by dragging the timeline bar all the way to the left. Then use your right arrow to move from the tiniest known particles in our universe, up to the edge of the known universe.

Cool.

My Lefty friends would look at that and say see we're not that significant.  I look at that and think all that created vastness -- wow!  And out of all of that He died for us.

Heh, neat.  It's kind of fun to move it a little faster once you've examined it in detail!

I like to think when I drink water I drink Mickey Mouse heads.

Here's a similar one I found awhile back.  It's focused on biology, and goes from a coffee bean down to a carbon atom.  It's only a small subset of the other scale, but it has better graphics.
