Looking for ideas to make a really cool site for myself

I am looking to morph from a strong C# WinForms developer into a WebForms and ASP.NET website developer.  So I intend to study JavaScript, ASP.NET and other technologies as needed to realized this goal.  I have some time but will still work on it with urgency: hence this post.

I will get myself an ASP.NET ISP to host a website that will showcase my abilities with a variety of technologies, using ASP.NET.

Can someone suggest some really cool ideas on what kind of controls and features I should consider while doing this?  I want to roll this out in phases, with posting my resume as one of the first.  But I'd like to quickly thereafter come out with some new pages to demonstrate some other cool things.

What comes to mind?  I will learn what I need to as I work to deploy these features, so I will not be untruthful in the slightest.  I hope to land a job as a contract developer for a company or to interest people in hiring me to do some freelance website development work.

Your suggestions would be appreciated.  No idea is out of bounds!

I have not worked with Silverlight, but imagine that I would need to if I were to make a really cool showcase website for myself.

Thanks,
