Barclay's was in the process of updating one of their legacy applications.
This application was a Visual Basic application from 1999.

The application allowed bankers to evaluate the risk of lending money to various clients.

This application used a
card-stack presentation for the different rules on the Home Page.

The application used a web-based spreadsheet embedded right in the application to enable the bankers to use an application they were already familiar with.

This was very successful.
