I envy your range of selection, Spark.
I'm too penny-less to go about purchasing shirts of that sort, though I do have some fabric-paint converter fluid for acrylics, and plenty of types of acrylic paint to spare. I also have a pile of black shirts set aside for just a use. Maybe it's time to get to work.
I do have my sights set on producing a larger handheld projector, and acquiring some 35 mm slides (reasonable quality or greater) of 'Tron Lives' with the T emblem, 'Tron Lives' in digital graffiti, red/pink and blue. I'd aim for a 200 lumen light at the least, preferably of a long/focussed casting variety... Which, I understand, would require some saving. Oh well. I don't mind at all.
I seem dead-set on producing a functional unit and carrying case (or one primary case, and two secondary holsters for a group), and having them 'strike' some meaningful targets. It's just a dream, but I'd love to see it happen.
It might even be good to see those shipped about, from group to group. We could chronicle it's travels (on some blog or media or another). It would be good to see us Programs each take our turn in literally leaving a mark... At least in visual media, anyhow.
