Arduino LED Coaster

This arduino controlled coaster was created to help me stay on top of my water consumption at work. Each LED is lit blue for exactly 1 hour before turning green, letting me know that I should have consumed one 8oz glass by he time the next led is lit. By the end of the work day I should have finished eight 8oz glasses. If you go over 8 hours, a new color is introduced to help in keeping track. The timer was sped up for the sake of the video.

I had a co-worker that loved the design but doesn't drink much water. However, she takes medication so I changed the timer to suit her needs. Now whenever the led is lit she knows to take her meds. How will you use the coaster?
