Ambigram?  I have never seen this word before.  Wow!

Word of the Day #2 added at 2:22 pm

am·​bi·​gram /ˈam-bə-ˌgram / plural ambigrams = something (such as an image of a written word or phrase) that can be oriented in either of two ways for viewing or reading.  When flipped upside down, it can create the same image or may form a new image entirely.  A very basic ambigram is the word "MOM" which can be flipped to say "WOW." — Hat tip to Jean Millner for this new-to-me word (posted on Facebook).
