|In this ambigram I attempt to capture the relationship between the two keywords, so that the black (safe) word CATCH forms part of the red (danger signal) word TRY. The starting point was the middle T in CATCH which easily became the long T of TRY. What had to be done with the C-R and H-Y was then obvious, but took a long time to achieve satisfactory recognition of both letters. Letter spacing and height also had to be fiddled with. The leading C of CATCH of course had to be made to match the later C. I am not completely satisfied with the R, but if you squint a bit it looks ok.
