How your heart beat now?

Each ellipse represent my heart rate.
I remapped my heart rate in the range 0-225 to change alpha value and color mode as my heart rate.
When ellipse are gray mode, my heart rate is normal (between 60-85). Brighter is Faster here.
Once my heart rate is over normal range (85), the color mode turns into HSB mode and change H value to highlight current value.

Here’s simple graph for my heart rate monitor. The hight of each bar represent actual heart rate. You can see my heart rate is rapidly faster while I running.
