This is such a fun marble, soooo many space formations and creatures to explore within. You'll really enjoy this one! Take a look at all of the pics, you'll see a lot of neat things. Unfortunately, there is a light scratch about a 1/2" long on the lens, so I discounted the price on this marble quite a bit. It's difficult to see in regular lighting, but shows up when you shine a light down in the vortex. A bummer, but it's very, very minor, and allows you to get a fantastic price on such a sweet marble.
