Mouse+Diagonal+Problem

A mouse crosses diagonally across a rectangular floor with a zillion square tiles. How many tiles does he touch? This is rich problem from: http://www.ohiorc.org/pm/math/richProblemMath.aspx?pmrid=56

My friend David Cox posed (a short version of) it on the [|GeoGebra forum] and got many, many responses.

I am just posting a couple here and have made the algebra view visible so that people can see how elegant these applets are: media type="custom" key="11431522"

This one includes the possibility of rectangular tiles. media type="custom" key="11431622"

Amazing - the GeoGebra community is simply amazing.
