A light that warms no matter where they’ve gone

(Biking) Pretty cold in the shadow… maybe I could write a tool to plan routes based on maximum sunlight? It’s easy to calculate the sun’s position, so we just need very precise topographic data and a good algorithm to to approximate our own position on the map anytime. Hmm. The prototype should be done in a few months. Or, I just hold on for five minutes until I am in the sun again.

That coldness doesn’t only make your limbs lazy…
