Here's the idea: Strap a laptop stand to a tree. Blammo! That's it!
Well everyone (especially around instructables) always talks about how bad sitting is for you, so everyone makes standing desks. But, you know what else seriously lowers your quality of life? Being trapped indoors all the time! Now you can go do your work, stand up, and enjoy the amazing world around you!
Dissertation Writing: This idea originally came up because I am now starting to write my dissertation. I figured that I would feel like a pretty big phony if, while writing a book about how great it is to be outdoors with nature, I was sitting inside my sterile house for the whole semester. This gives me a way to write down my ideas situated in the gorgeous world which I am describing (psst. the second image is a GIF, look how beautiful fall is in Atlanta!). Hopefully doing this will prevent me from including some erroneous assumptions about the world in my manuscript.
Jungle Re-programming: I also started having this idea during my field research in Panama. Sometimes it became necessary to reprogram some of our equipment, but jungles are that great for sitting down indian style, and laptops need a lap (or something else). The best we found was the hood of a truck, but that isn't always there. Being able to toss up a little station anywhere could be really awesome! I can't wait to test it out next summer!
As with everything I do it goes right into the public domain. The laptop holder was generously provided by Mathew Owen from Fablab: http://www.thingiverse.com/thing:49812/#files and is under a Creative Commons Attribution license. Everything else, especially the concept of tie-tree-to-laptop, is open-hardware and free for anyone to do anything with. Importantly, I want the hardware to be open so that no trolls can come around and sit on a patent, and try to stop other people from making cool tree desks. Also, this is the earliest design, and it has some flaws, so it'd be great to see what people come up with.
Also, this isn't the craziest new idea, I'm sure there's a bunch already out there, hopefully they can point me to those and I can see the even better ideas that may be lurking!
