I know tkiz is not that difficult but I dont have the time to deal with it right now.
So I am giving away 0.003-0.004 BTC to the first person who posts Tkiz code for an image which resembles but does not equal this image:

Some comments what individual commands do are also required.
Also I want that arrows to the left (lo) are a little different from the ones to the right, without using colors.
If somebody improves upon the first solution considerably (my choice) I will send him 0.002 BTC.
I also keep the right to chose that a solution isn't sufficient.
Please only post the code, not the resulting image.
Thank you for your time.
