It seems like there are three different versions of this Poly Z Vision app. This free one isn't as awesome as the paid ones, but I guess that's why it's free haha. Anyway, this app lets you play around with fractals (which are images that have the same structure at all resolutions, think a snowflake). You're a bit more limited in the amount of manipulation available, but its still a lot of fun! Good for kids and adults alike. As I mentioned in the other review, the interface could be a little more streamlined, but that's just nitpicking. 5 stars
