Android Dice Roll

Layout Take a look into android app [login to view URL] I attached screenshot here. I need two dice (white, black dots), placed vertically (as on the screenshot). Application should not react on screen rotation and only work in the portrait mode. Die size is computed by formula (W is width of the screen, H - height of the screen, d - dice size): 2*d + 2*0.08*d+0.04*d=H. If d+d*0.08*2 > W, then d defined by the last formula (or, min of both formulas). Space between window upper border and top dice top border should be equal to the space between window bottom border and bottom border of the bottom dice (red on the screenshot). Height ratio of space between the die's borders (green) and lower/upper border is 1:2. Only two dices are needed. Actions User can roll any dice. It spins, depending on initial speed, decaying, no longer than 800ms and should stop random face straight to the user. That's it! I basically want to spin dice randomly. Die shape Dice is not a plain cube. It's corners are cut by the plane. Let's take a diagonal of the cube and take 3% of it's size from the vertex - point A. and cut cube with plane perpendicular to the diagonal containing the point A. 3D Scene with cubes should have a light somewhere to see clearly dice' cut angles. It's good to have point on the dice embossed, but not necessary.
