graffiti

I found this stenciled on the sidewalk behind the outdoor organ pavilion at Balboa Park yesterday:

What does this mean?  I must be missing something.  If this is purely educational graffiti, why would someone bother to cut a custom stencil and spray-paint it on a back sidewalk?  Educational graffiti? 

Do feel free to take me aside and say "Never use that phrase in public again, k?" (Because I need to know that, too...)

How will I sleep at night until I understand?  Is that why they did it?

I guess you could compare a couple of phases of mitosis to a beach ball (anaphase and/or metaphase). But then I don't understand why they would graffiti about it.

I wonder if the perpetrators were looking at you saying, "hey - made you think"...

I'd love to know too.

Maybe it's a secret code (well, obviously), It would be a great starting point for a a story.

I'd love to go to Balboa someday.

Sadly, you're right. This is totally something our husbands would laugh themselves silly over and then fail to explain properly. Oh, we've met the geeks - then we married them.

As a side note, if you search for "find mitosis in your beachball" you find a lesson plan for explaining mitosis using beachballs. I can't tell if I should find that interesting or disturbing.
