Add more uncertainty into your spreadsheets

I came across http://ift.tt/1QYNmhq today. Its like a simplified online open-source version of @risk (which makes me wonder if @risk will be @risk). It supports normal and uniform distributions, but also supports enough other functions that you could create other distributions if you put the time into it. And its free to use.
