Colorful marbles roll away as the countdown progresses.
The Marbles Timer displays a grid of 25 glossy, glass-like marbles in ten different colors. As the countdown ticks, marbles disappear -- rolling away one by one until none are left. The 3D-style shading with radial gradients and highlights gives each marble a tactile, toy-box feel that kids and adults find engaging.
