Frank Mariate has been so kind to share some images from apps he has developed with X#. You can find these in the Examples section on this website.
He will be demonstrating his apps during the "Application Show" at the XBase Future conference in Cologne as well.
unfortunately at the moment I have no big application to share, but you can find a few small samples here:

And if you install XIDE, there are a few samples also. What do you need exactly?
