This is pretty intuitive and useful, I think. I would suggest swapping to an angle equal to half the angle of the turn once your approach is within a certain distance, to show the user what is coming up around that turn. Frequently you need to turn then turn, so seeing 'ahead' a bit would be cool
Zero chance you can patent this though.
What problem does it solve tho ?
ok this is nice

Cute. Only runs at about 1fps on my 5yo LG phone but it's a miracle it runs at all.
