Osmo is an educational game for the iPad that has some nice features. It encourages creative thinking and social interaction by turning any physical object into a digitally connected game piece. You can see more on how it works here: https://www.youtube.com/watch?v=CbwIJMz9PAQ
You can play the games on any surface and with multiple people. It's very easy to use and a lot of fun. I played with it with some friends and they were impressed.
It comes with three games to start with:
Arrange tangible puzzle pieces into matching on‑screen shapes. Play with a friend or challenge yourself to more advanced levels as your handy‑work lights up with each victory.
Use your creative noggin and inventive objects like a hand‑drawn basket, grandma's glasses, dad's keys, or anything around you to guide falling on‑screen balls into targeted zones.
Be the first to guess and spell out the on‑screen hidden word by tossing down real‑life letters faster than your friends. A related picture gives the clue.

In addition - after you take a look at the site more, comment (on Google+ and/or Twitter) with what your favorite Osmo feature is, or how you want to use it and I will randomly select one person to win a free Osmo. (You must live in the US, sorry). So, comment away!
