Portfolio Projects?

[PandaBear]

Just curious if anyone had any idea of some sites that may have projects posted that aren't neccessarily real projects but something that has a listing of potential 'real world' projects, with some specs to go from...in order to help build your portfolio?

Kinda like this one except with working links: http://desktoppub.about.com/od/portfolios/a/portfolio_stuff.htm
