This is just a goofy thing I cooked up over the weekend. It's kind of like a screensaver, but with more reading and sliders. (It's not terribly efficient, so expect phone batteries to take a hit!)
Very nice, I could suggest two more factors influencing growth that are important for plants: geotropism and phototropism.
Geotropism basically makes plants grow away from the source of gravity, and phototropism makes them grow towards light (and that is usually reversed for roots).
