Terry – a rotational ambigram.
This design is a completely different style for me. I wanted to create something that looks like it is scrawled but, actually, it is quite intricate. The entire piece is identical when viewed upside-down, including the messy background!
My favourite ambigrams are ones when there is not a direct letter-for-letter translation - like this one. An "R" transforms into both an "E" and an "R".
