Keynote Demos
PhotoBooth Application
The PhotoBooth application demonstrates some of the fun things you can do with the new WebCam and Microphone support in Silverlight 4. It allows you to record videos and take photos within the browser – and then optionally apply effects to them (for example: the bulge effect below). For kicks you can publish a photo of any of the pictures to Twitter 
BarCode Scanner
The BarCode Scanner application also uses the new WebCam support in Silverlight 4. It allows you to scan an ISBN barcode from the back of a book, and will then use Amazon web-services to look up details about the book online:
Rich Notepad
The rich notepad application shows off some of the new text editing features in Silverlight 4. It allows you to edit rich text within the browser, supports Bidi text (including Arabic and Hebrew), supports both left-to-right and right-to-left control layout (RTL is show below – notice how the scroll-bar is on the left hand side of the screen), supports programmatic copy/paste to the system clipboard, custom right-click context menus, printing, and drag/drop of files from the desktop into the browser to edit:
HTML Hosting
The HTML Hosting application shows off using the new Silverlight 4 webbrowser control in an out of browser application (note: you must run the application out of the browser for it to work). It allows you to use the control both interactively (meaning you can click the HTML within it and run it like an application). It also allows you to use the hosted HTML as a brush that you can apply to other Silverlight controls. For fun you can click the MSDN.com tab below and you’ll get rick-rolled to YouTube. You can still use the HTML as a brush and carve it up into a jigsaw – even though the video is still playing (using Flash hosted within the HTML):
