It depends a bit on your distro and policy model.

But generally you can demonstrate how TE enforces integrity for targeted
system daemons.

If you use strict policy you can also enforce integrity for user
processes. You can also demonstrate role based access control.

You can demonstrate how MCS can be useful to restrict processes access
to objects.

If you use MLS model you can demonstrate enforcement of confidentiality.

I never actually connected to play machine but i gather it mapped the
root Linux login to the user_u SELinux user.

There are a lot of ways to demonstrate SELinux. You could restrict a
simple hello world shell script and shows what happens if you extend the
script to make it do something it is not intended to do.

Same goes for webapplications. You could write a webapp and make it do
something that SELinux policy does not allow it to do.

Generally TE tries to prevent privilege escalation. It restricts processes.
