Geometry: construction tutor lite

Today I looked at Geometry: construction tutor lite which is the free version of Geometry: construction tutor.  The lite version allows access to the first two sections of the package which for me are the most important.  The first section is on constructing a line segment, a perpendicular bisector, dividing a segment into an equal number of parts, construction a perpendicular line through a point or an external point or constructing a parallel line through a point.  The second section covers copying an angle, bisecting an angle, constructing a 30, 45, 60 and 90 degree angles. 
It has two modes, one is a demonstration mode which has play buttons so you can show each move, one step at at time and then it has a practice mode so you can practice using it yourself.  It actually has a virtual compass, lines, etc.  If you do not do the construction using the proper tools, it will let you know that you did not do it properly. 
This is nice because I do not have to keep track of compasses, pencils for compasses, or put up with broken implements. It also shows each student the steps so I have more time to circulate and answer questions.
