Other tools I've seen simply provide a link which displays an hourglass upon clicking and some moments later you have your results in a nice simple table. Great, thank you, I'll be on my way now...
That's why I was very pleasantly surprised to learn about speedtest.net. They did this simple application in a big way. Several layers of information are presented in clear, aesthetically pleasing visual design.
They effectively utilized this one moment of my attention spark a greater interest than just what I came there for. I had to stick around to play around a little bit and learned some interesting things in the process.What's most interesting to me is that this design allowed them offer more complex features with out taking a hit on UI complexity!
Word of this design got out quick, a single digg.com posting with a reference to this site redesign got 4783 "diggs"; not bad!
