I am a programmer with experience in .NET and several programming languages. I am currently creating a number of demo programs to demonstrate my skill in various areas for future jobs, should I ever leave my current one. I want to create a website using asp.net (with C# running things behind the scenes). But I need an idea. The idea or concept needs to be clean and completely legal and something that could demonstrate my abilities to interest employers. This will never be put in production in the 'real world' so I am not worried about trying to sell actual products or have innovative ideas to draw new customers. This is simply a mock-up website that I can host on one of my computers to demonstrate my talents during job interviews. Any ideas? Please do not suggest a blog or things that require Flash. The only thing I can currently think of is a simulated online store selling made-up products from made-up companies. This would allow me to demonstrate databases programming and design for products/categories, securely handling user accounts/passwords, and other 'real world' skills. However, if other ideas exist, I would appreciate your generosity if you would give them to me. Thank you.
