Here are four new ambigrams I have created over the past few days. All related in some ways to things I have been thinking about. The first two are for STEM (an acronym for Science, Technology, Engineering & Mathematics) and STEAM (Science, Technology, Engineering, Art & Mathematics). The next two are for Research and Gandhi. Why I have been thinking of Gandhi is a long and complex story that I shall leave for a later date. Anyway, here are the new ambigrams.
