Yes, the latest internal builds feature the source of both SPA applications - html is located in /examples/web/spa, the rest in /examples/content/spa. You can also navigate to the demos trough the Examples index - check the bottom of the page. However, I just discovered that the Sushi's html and js files are a bit messed up after the generation and will not work out of the box. I'm attaching here the fixed versions - just extract the zip in the examples folder.
All the best,
