Stroll on!
My days of public projectoring are now but a dim memory, however It arms the cockles of me heart to see such enthusiasm.
I'm not sure about programmable text generating lasers, they were new-hat when I last fiddled with such things. I'll ask about. The Baltic's original mission statement said that they would loan/hire out projectors to Artists, but the capital A is in reference to the fact that you have to be a "proper" artist. So someone with a track record would be handy.
I can probably get me hands on a genny, so powersupply shouldn't be a problem. There is the perfect spot on the Quayside, just by the yacht (what a strangely spelled word) club. Iv'e seen a van there doing the biz with a big slide projector.
As you should gather, I'm up for it.
