1. Ivo, I tried the series thing myself with my
Miss Coke; it ended up a dead end and a mental trap to boot.
http://www.roma57.com/coke.htmlFrankly, it (a series) eventually becomes forced, at which point it loses (at least for me, who has to make the snaps) its value because one tries too hard and it shows. I think art has to look fluid, easy and natural.
2. I also failed to make any connection with rubber. Unless you want to limit the interest to those already in the know, perhaps the way around it is to start with a proposition laying out your intentions.
For that to work fluently, you'll really need to keep the images grouped together at all times, along with the explanatory introduction. Showing a single image at a time will not cut it because its success then depends on the viewer always staying aware of the concept, which it a pretty big wish for anyone.
