Martin has now progressed to a "Relocator - advanced student".
He has worked out you can get to all the things put out of reach by pushing a chair or box or anything that will move closer to the desired object and climbing higher. The dining chairs are pretty heavy but he just pushes harder. As you can see here, he can now reach the computer. This is why everyone has a password and the screensaver is password protected too. In this small way we have some protection from marauding fingers. Although the screen does have interesting finger and hand shaped prints obscuring the view.
