The program is easy to navigate. There's a color picker button that brings up a full-screen spectrum to choose from, and you can save colors to go back to them later. There are options for single color, multi-color, or random color sand. You control the thickness of the sand piles by how fast or slow you drag your mouse, or double clicking starts an automatic flow. Watching the falling sand is mesmerizing.
There are some crazy good works of art that have been shared on the website. Mine isn't one of them, but I had a lot of fun doing it.
