Recently i got a chance to know about ink space android app. Its really funny and amaze you. Ink Space is a small experimental drawing tool which uses the accelerometer on your android device to move the drawings you make in 3d.
The project itself it fairly straight forward you can draw, move the phone by tilting in different directions, adjust line that you are drawing, create an animated line which pulses and re-draws itself and record an animated gif of whatever you make. Double-tapping (or hitting the trash icon in the menu) clears the app. Just give a try and you love this app.
Now it have very limited features and we can expect more features in updates.
