Ok folks, so this is the update on how I will be proceding for the Ellis Generator in my city.
I have made 5 talismans out of wood. Usually I do a finished job but this time I kept it rough. I acquired a trowel (and believe me, that was a hard word to remember for a francophone man) and have decided that I would plant the talisans as seeds, in 5 designated public parcs. The parks themselves don't turn out to be a rectangle, but more like some sort of 4-sided irregular polygon. Whatever, it's still going to generate.
On the reverse, I decided to use the sigil for attaining gnosis as mentioned in Liber Sigilum. It has a magical-enducing feel to it (at least for me) and if this ellisian generator is to make more magic in this city, having a sigil that puts people into the right state of mind is a good helpful thing IMHO. The obverse were as per the ellisian generator specs.
(EDIT : I forgot to mention that on the side of the talismans I etched 5 Laguz runes, to represent Love Life Light Liberty and Laughter. You can see some of them a bit.)
AND FROM THIS SEED, SPRING FORTH THE WORLDS !

Then, technically, we're supposed to put up a whole bunch of signs. So I decided to get a pack of playing cards. On the back of the cards (I chose a red pattern, because Red Queen and stuff) and I put the Ellis Sigil on each one. Then on the face of the cards, I decided to write with a black sharpie all sorts of DKMU slogans. On some cards I wrote whole slogans and on others I wrote only a word, a part of the slogan. However, I'll be mixing up the cards and spreading the cards out pretty far, as I've chosen a rather big perimeter for the ellisian generator. The point of this is to send people out on a wild goose chase - if they find one or two cards, they'll want to find others. Eventually just maybe google something and wind up here.
I cheated on two cards, however, as one the 5 of spades I added "Hail Eris" and the black joker says, "The Game." Please don't be too harsh on me for my handwriting. Doing the same sigil over and over again while repeating the mantra "and upon this mark I unite the worlds" put me in a really strange hypnotic state and made my drawings rather woozy. As for the face side of the cards, well let's just say I got a lot of crap from my elementary school teachers when I was a kid because I write in "chicken feet." *sigh* Anyways, here are the pics :


So these will be taped to light posts with the back out, so that whosoever is curious about the LS will be able to unstick it and look at its face. If the person does have the "collector's instinct" inside them, they'll want to find the others and maybe find their way back here or something. Who knows, maybe they'll try magic as a tool for empowerment ?
My next step is to write "activation formulae" so as to "charge" the talismans and the cards prior to planting / burying or taping them to a post. (Could this be the actual origin of the word, "posting"?)
My idea so far is a simple, 2 or 3 sentence formula as I bury the talismans, where I put all of my energy into it. The deck of cards might siimply be charged at my house temple prior to posting, a few days later or something.
I hope this post is as interesting to you all as I am having fun doing this ritual. Some days I look at myself and think, "fuck shit I'm crazy, and I love it !" Today was one of those days.
Cheers !
