Show-off of festival build!

Since there is no place to put finished builds, I'll show it off here. I think it might be of interest to DIY'ers in this forum. Please ask questions as you wish! 
So- at a Danish festival Called Roskilde festival, me and some friends ran a camp project for a few years. We got access to the festival site 2 months prior to the festival, which allowed us to build our theme camp. 
Our name is "Camp Badeanstalten - Roskildes vådeste camp" Which roughly translates to "Camp bathhouse - Wettest camp of the festival". 
We have a life-guard tower with build in speakers, monitors on the deck, motion activated LED lights inside, solar panels, a battery power bank to last us a week, a Nanoleaf palm tree build t

o be waterproof, our own tank of water with a pump, led strips all around the top, and a wi-fi router to controll everything wirelessly. It also hooks up to our external - mobile - speaker system. This system is controlled via a build in ipad, and has charging for about 10 phones at a time. It has it's own solar panel, and tracks the location of the sun, to automaticly rotate the solar panel, via an actuator.

Sadly, we had to tear it down this year. But it was a really fun project, and as two engineers, this has been quite the playground!
