Freezing yogurt/fruit?

I wasnt sure how to title this so it'd make sense. I read something in a cooking magazine (or thought I did, looked back through it and couldnt find it) that said you can make your own freezer pops by blending some yogurt with fruit puree and putting it in those popsicle containers you can buy at the store. Has anyone heard of anything like this with yogurt? I want to try it but I've gotta get the popsicle tray thing first. I tried to google it but just got regular popsicle recipes.

Here is a google search that has a number of recipes that you are seeking
