Sure, if you define "words" as a binary "did you see lights?" question. See jawns comment for what this study was actually about; certainly not the transmission of actual words. Deceptive headline and article. EDIT: After reading the linked study, I was too harsh; they did actually transmit the words (with a 2-11% error rate) via this binary "lights" mechanism, so you could use such a mechanism to communicate in Morse code. Just not for the sort of subliminal communication inferred in the article.
