Engaging interactive activities/games and intuitive interface for Android

We are looking at designing as series of activities for adults with Austin. The idea is a series of games activities: FX Effect You touch the screen with your finger and you see different effects such as changing colours and changing designs. Music Effect We also will use music such as a piano that people and play or other musical instruments. Custom Games We will send you some custom games that will be need to be [login to view URL] games. Memory Games Some standard memory and card matching games. We will supply all images. You can use assets that can be customized and are currently available (or need to be purchased) to speed up the completion of this project, we don’t need to reinvent the wheel. The idea is to bundle all the games in one package and load it on a android tablet. We currently sell a education software system for Austin. This would be a game program we could include after the education program has been complete by the student. This is a stand alone program loaded onto a android tablet. We are looking for someone who can source assets that are currently available and create new assets fast and complete the who project. I don’t want this program looking like a kids game. So WOW me. Budget between $500-$2000
