I'm sorry I've turned in no help Alex, I really dont have ideas for puzzle games, I've never got into one...
In my last post what I said about "artist boards" really reflected more of how I feel....I kinda feel alienated by the theme, I really dont know what makes a puzzler tick.
I still stand by what I said, to ask for puzzle ideas in an artist board....well, let's just say I dont think you'll get much feedback, I think you should put more yourself in this phase, and just wait for artistic implementation phases to really expect comunity feedback to be the driving force.
I do have some thoughts on how to improve some of the ideas posted though, but since you mentioned polls I guess we should wait for a diferent phase for that.
I just had an idea...at an artist board we may not be able to come up with a puzzler out of the blue, but I find it's always easier to say what NOT to do, than to propose something....so maybe we should make decisions about the game slowly, start by asking general design questions, then narrow it down to specifics as the activity advances, that way no one really has to create a big idea, but we can advance a little faster.
