At the Maker Faire a couple of months ago, they had two 9-foot-tall Tesla coil towers.

The towers were about 25 feet apart and they would fire them off for 10 minutes every hour.

They were quite spectacular!

Since I don't have my photos of that handy, I'll just attach an "oldie but a goodie".

Also, did you see the movie "The Prestige"?
Tesla played a pivotal role in that... Interesting movie.
