From the sounds of it, we will need a few divisions of material.
A Manifesto, basically about us as a group. This may also be important for our group as a whole, as it would give new people - or any possible more formal persons - something to refer to... Or refer to us by.
A formal Petition document, outlining exactly what we want, and what values we see this effort as embodying.
A 'mobile' petition document, likely of a more portable sort, or more presentable sort, for handing out to others, or showing to others, etc. This could also be incorporated into pamphlets.
Leaflets of various kinds for handing out, or posting; one side could be more graphics-oriented (eye-catching). Generally such 'spam' only gets a sole glance by people.
Perhaps also post-board type images, for putting up around the community in certain areas, or for just taping around light-fixtures. This would have to be of a hardy, professional-quality material, I believe. I'd certainly pay for a few if I had a document on hand.
I liked the one idea of finding Disney's employees' cars and putting some under their windshield-wipers.

(I wouldn't see that effort as invasive; although we want them to notice us, we also don't want to spook them or cause any grief - that is certainly not our goal, as I personally see it.)
.. Although, by this point, and looking at the reactions of some fans, Disney would certainly deserve to have their chains rattled a little.

Or, if we had a more concise target, at least that executive or persons behind it, anyhow. (I mean that in a non-malicious way, of course.)
EDIT: If we are going to share drafts of text or layout, what programs/formats are we using? My computer is as old as the rocks... Well, maybe not that bad, but still. I'd think that RTF would be the most basic file transfer type. DOCs can have their incompatibilities, and TXT is too basic. Then again, drafts are drafts, and I only expect them to be for basic information and layout; those who are more skilled can see to image and finished development.
Is there any Program here good in basic graphics for incorporation into the document? Is there anyone who could work with some slick digital artwork featuring Tron, Beck, both, or other characters or design layouts?
EDIT 2: Some reading indicates that most 35mm slides are at 4096 X 2730 pixels. This is indicated elsewhere at being the high-quality equivalent of a 16X24 inch print. I am not familiar with these conversions or basis of common/quality resolution.
A full display of 'Tron Lives' (or equivalent of our message) Would presumably require an image of at least 30 by 20 feet (10m x 6.6 m). I have an old computer. The highest resolution file my old box of a computer could handle is a 72 px/inch at 400/340 inches (33 ft. x 28 ft - or 11m x 10.5m). I would also need a way to transfer this file and have it converted into a slide.
I still have yet to call around at the Photography Labs in my city and see what I can get, and if a slide at that resolution is possible. I also intend to keep an eye out for any available slide projectors, and if they take any slides greater than 35mm.
Some sites indicate 'Superslides' for multimedia displays and presentation at superslides at 16 megapixels or 4096 X 4096.
