Lucas Shapes and Sound (SS) displays shapes on the screen. Tap the shape to play a sound. Drag the shape to move in 3D. Double tap the shape for fireworks with sound. Made for my grandson's 2nd birthday. Parent controls require a 3 sec long press to keep kids from accessing the settings. Parents can mute the sound, select letter/number block only, add word list and add child and parents names for a special message on the screen.
