What kind of experimental type shall I do?

Being that in this post-modern society/information saturated age, type is everywhere, and there's so much of it, what would it mean to create a typeface that would be readable but will kind of disappear to ease the eyes and make reading more fun?

Two ideas on that:
1. when type becomes art it's less type looking and more visual (it should still be readable though)
2. when you take a font, see how much of it you can subtract before it becomes illegible

Examples links of those ideas:

I'm interesting in advertising type and signage stuff that is more minimal and simple, that makes the world of reading a lot easier.

Here's some more examples where the type doesn't scream at you, instead it's part of the design:
