On the net, there are many alienware type start buttons / orbs to choose from for 100 % display size, 
but I don't see any for 125% and 150% sizes.
These user picture avatars have transparent background (except for the white one), 
so they can be resized, brightness, color/tint changed, then made into personal start buttons.
