This is the Jumpin Jacks AO.
It has 3 buttons: Top one of the guy sitting down is the Ground Sits. The middle white button is the Menu. The bottom button is the On/Off button.
To add animations to the AO is easy. Just rezz on the ground and then Edit and find the Contents tab. In the Contents folder you will see 2 scripts Core and Interface, you dont need to worry with those. Also is a Default note card, you will work with that.
Right click the Default note card and you see something like this. Its all the catagories that the animations will be sorted into. This is where you will add the animation name.
