Although many places in scripture and Talmud speak of various parts of G-d's body (the Hand of G-d, G-d's wings, etc.) or speak of G-d in anthropomorphic terms (G-d walking in the garden of Eden, G-d laying tefillin, etc.), Judaism firmly maintains that G-d has no body. Any reference to G-d's body is simply a figure of speech, a means of making G-d's actions more comprehensible to beings living in a material world. Much of Rambam's Guide for the Perplexed is devoted to explaining each of these anthropomorphic references and proving that they should be understood figuratively.
We are forbidden to represent G-d in a physical form. That is considered idolatry. The sin of the Golden Calf incident was not that the people chose another deity, but that they tried to represent G-d in a physical form.
