Just discovered fun sites

I found a few sites today that I see potential use with my students.
The first is Kerpoof. A fellow teacher described it as a bit like KidPix.
I see it as a way for kids (of all ages) to make their own comic.
You can make just a picture with the backgrounds and images supplied.
You can even make a story and short animated movie. I have not tried those yet. This weekend.
The second is Voki. I have not gone into much depth with the site but I see that it may be used with my 6th graders.
The last is one that I have known about for some time but have only watched my students use the site. Millsberry is the name. The students have created a virtual persona that they interact with. It seems like a kids version of The Sims or Second Life. I see where this could be a way to use concepts learned in the classroom in a "real" world setting. We'll have to see about that.
