I found a paper on the Mandelbrot set and computability, I understand very little but maybe Bruno would be able to follow it:
http://arxiv.org/abs/cs.CC/0604003

The same author has a shorter outline or slides for a presentation on this subject at http://www.cs.swan.ac.uk/cie06/files/d37/PHP_MandelbrotCiE2006Swansea_Jul2006.pdf and at the end he asks the question "If M (Mandelbrot set) not Q-computable, can the Halting Problem be reduced to determining membership of (intersection of M and Q^2), i.e. how powerful a 'hypercomputer' is the Mandelbrot set?" I believe Q^2 here just refers to the set of all possible pairs of rational numbers. Maybe by "reducing" the Halting Problem he means that for any Turing machine + input, there might be some rule that would translate it into a pair of rational numbers such that the computation will halt iff the pair is included in the Mandelbrot set? Whatever he means, it sounds like he's saying it's an open question...
