A very good idea. [youtube http://www.youtube.com/watch?v=TcLV1CsGCJg&w=640&h=390]
I haven't checked it out completely, but I'm inspired to give it a try as an alternative to a PDF portfolio.
As I am creating my portfolio (spending my weekend at the labs) I have also been fiddling with WIX.
Hopefully, after this weekend. I will have an end result (unlikely.)
