An art-piece t-shirt or beanie I screen print with your choice of several designs, specify which and size, as well as the first reward (email, cartoons). I say art-piece because it may be one from the thrift-store that I print on, and you're not allowed to do consignment here. Just so that's understood.. If outside U.S. and pledge more than once at this level, you'll get three for two or four for three to account for the cost of shipping per pledge when they can obviously all be shipped in one.
A homemade, hippie/punk-zine-style booklet of my funny cartoons and such (perhaps bound in hemp or recycled blue-jean), autographed of course: there may be staples, zip-ties, elmer's glue, or all of the above involved, just so there are no surprises. It will likely be crude and juvenile but amusing, if you're into that sorta thing.. i'll try to make sure it's the most ridiculous thing on yer coffee table, and no two will be alike!
A mega-sized version of my homemade, hippie-zine-book of my funny cartoons and such with an autographed original piece as the last page, and a t-shirt/beanie of your choice, delivered as soon as I'm funded, as well as the promise (underlined) of a first-generation "Tree-zel" when and if (emphasis on when and if) it reaches production.
All of the above and a custom-made pre-production "Tree-zel," assembled from whatever I find with which to make it. The idea is extreme portability, so it will be light, collapse small and probably come in a cinch-sak, as I intend for the production model as well. I spent zero dollars on my crude mock-up, so it's kinda rough-looking, but yours will have an actual ball joint that I order rather than my rigged one, the x-brace holder assembly will not be made of hacked-up curtain rods, and i'm sure I can get some minor welding done somewhere so no wooden blocks are involved. I will likely use a simple TV mount, the kind that sits flush with the wall (ten bucks at the A/V store) as the base, and will bust out the sewing machine to make the backpack straps look nice. I will also make it tripod-compatible/adaptable for you, perhaps even buying a thrift-shop tripod and modifying it into a treezel, so it's both!
