This site is pretty cool.
It allows you to see your, for that matter, any website of your choice in 60 odd browsers. It has support for Linux and Mac (oh my god.. do people sell them!!!!) .
Just submit the website you want to view and the job is queued. You can even set the maximum wait time. Once the wait time elapses, the screenshots are displayed on your browser. You can also see your ticket in the queue.
