The Wrong Side of my Car
The blog that wants to go obsolete
The far side of the windshield
Some observations of the far side of the windshield. I can’t read people’s minds, so I filled in some details…
Every day John Doe catches the bus to work on Glenfield Road. As usual in the morning he has to cross the road.

So what I want to do is 2 things:
- Turn the height into a color map,
- add relief shading to emphasize local relief.
