Sand Timer (Hourglass) Countdown
The hourglass is humanity's oldest countdown device, dating back to at least the 8th century. This animated sand timer recreates the experience with flowing particle physics — watch individual grains stream through the neck and accumulate in the lower chamber. The visual progress is immediately intuitive, even from across a room. Choose from wooden, brass, or minimal glass frames, and adjust grain density and sand colour. The sand timer is a wonderful companion for meditation, classroom activities, and any moment where a calming visual countdown is more appropriate than flashing digits.
