Integers in a grid
Prove that there is a 11x11 grid filled with digits such that one can read the squares of 1,...,100 on it. Reading means there you can fix the starting square on the direction (8 possibilities) and go to that direction as many steps as you like. Solutions found by computer are allowed but I don't know enough programming to do it.

Sorry. I meant you fix the starting square and the direction.
