A square can easily be drawn in the plane so that its vertices have integer coordinates, but a short argument shows this to be impossible for the equilateral triangle (which however, can be drawn in R^3 with integer points for vertices).  In this talk we will see which polytopes are able to be embedded in some R^k so that all of their vertices are integer points.
