The results for the ACAC are in, a few days earlier than expected for a change. As always, the winning entries can be found on the ambigram.com results page. I was surprised most by Elwin Gill's design, a fully hand drawn piece with amazing detail. The following two ambigrams were my own submissions.
Naturally I had to do a city from my own country. Since it had to be a relatively well known city, the options were a bit limited; Amsterdam ought to be notable enough though. The design incorporates the three crosses and colour scheme from Amsterdam's flag and coat of arms.
A somewhat random choice, yet a fun ambigram to make. It was chained to allow for optimal readability. The letters around the x were the trickiest part, but came out pretty nicely. This ambigram also uses my favourite solution for the lower case a twice.
