Ambigram

An ambigram is a word, art form or other symbolic representation whose elements retain meaning when viewed or interpreted from a different direction, perspective, or orientation.

The meaning of the ambigram may either change, or remain the same, when viewed or interpreted from different perspectives.

Here are some articles and galleries about Ambigrams:
