Liquid is a funny graphic editor, in which control of brush is implemented
 by accelerometer or touchscreen. In our graphic editor there are realized
 basic drawing tools (brush, eraser, color tool) and additional (ice -local
 blur effect). Switching beetween accelerometer/touchscreen mode is implemented
 by shaking device on Z axis, also you can clear a screen by shaking on X axis
 and implement full screen blur by shaking on Y axis. To draw in accelerometer
 mode you must touch a screen in right bottom corner. And to change brush size
 you must touch a brush and wait for some time, then popup menu will appear.
