Beaded Sweatheart Soap?!?

I was cleaning my bathroom and was about to move the Sweetheart bar and I noticed something really neat. The entire bar had a beaded look to it! I'm assuming it's because of the moisture from the bathroom, but I've never seen any of my other soaps do this before.
I took some close up photos because I thought it looked so pretty.
You can kind of see where I touched it with my finger. LOL!

If you look close you can see the spot I touched.
