Could do something like that website, I think it’s Wu’s Penthouse or something where there is a one story template and anyone could go and design a floor and get it added…it ended up being bigger than the tallest building in the world. Make something like this that is for memorials, have a template for people to design from, but have it fill a different pattern than the tower. Like it could go horizontally, or fill an imaginary field, or make a line wrapping around the world....
I like the idea of doing something memorial related - you can tell from the prevalence of those memorial car-decals that people are interested in this type of thing.
