16 Segment Red
For the techies out there, here's a bright red 50 minutes countdown timer with a bright red 16 segment LCD font on a black background.
Great for helping keep students focused and motivated by working in class.
And if 50:00 isn't the right timer for you, it's easy to change it to whatever you need.
