On the technical side: You should really upgrade Symfony to version 2.7 (new LTS), the 2.1 you use is not supported aynmore. In the demo (production environment) you should hide the webtoolbar for security reasons.
How about screencapture gifs? Example: http://i.imgur.com/DsZx51m.gif
As far as the Symfony upgrade, great minds think alike: https://github.com/wealthbot-io/wealthbot/tree/feature/symfo...
don't think of the demo as production, it's just a test server with some dummy data, where you can play around with features of webo.
as open source projects we welcome all the help and as many pull requests as possible :)
the actual command it runs is: doctrine:fixtures:load
(which are in the Fixtures bundle).
the script which setups the demo data is located in vagrant/puphpet/files/exec-once
if you don't use vagrant you'll need to run that sort of setup manually
