-Welcome back to Polka Dot Day on "Camp TV."

Didn't that last activity just...hit the spot?

Well, here's something that should also do the trick.

Have you ever heard of Georges Seurat?

He was a French artist that lived in the late 1800s and he is famous for developing a style of painting called pointillism.

Seurat used a technique in which he applied small, distinct dots of color to his canvas to form an image.

Up close, you can see all the individual dots and colors, but when you move further away, your eyes can't see that level of detail anymore.

The dots create an optical illusion.

Your brain blends the dots together, mixing the colors and creating the full picture.

Another painter who used pointillism early on in her career is Belgian-born painter...

Both Seurat and Boch were painters from way back in the 1800s, but the technique and science they used to make their paintings is still being applied today.

Take a digital picture or computer screen, for example.

Both use lots of single dots to make a bigger picture, except, the dots are called pixels.

Pretty amazing, don't you think?

So, since today is all about dots, I thought we could do something crafty that uses them.

Dotty suggested we paint one of her favorite things -- a tree!

So, without further ado, let's get to the point.

You will need some paper, some nontoxic washable paint, some cotton swabs, a paintbrush, a pencil, and your imagination.

Start by making a tree trunk and branches by outlining your wrist and hand on a piece of paper, like this!

♪♪♪ Using a cotton swab, dot on some leaves.

If you don't have a cotton swab, feel free to use the tip of your finger, instead.

I like to add many different colors.

How many you use is up to you, but I say, when in doubt, add more dots.

♪♪♪ And there you have it -- your very own polka dot tree.

Spot-on, don't you think?

Enjoy your last few activities!
