Although we have a very high completion rate for the words, names and phrases used to make ambigrams on the FlipScript.com web site, we are always looking to improve further.
You can now create thousands of new ambigrams on the site. We have also updated the shape and kerning rules for some improbable edge cases, and even fixed some bugs with the artwork (if artwork can even have bugs!). Some of you wrote to let us know that the site was down when you visited during a short window last week while we were installing the updates, and we're glad to report back to you that everything is back up and running smoothly with the new updates in place.
By the way, if you ever encounter anything unusual with how one of our ambigram designs come out, please continue to let us know so we can take care of it. Also, please understand that from time-to-time, we need to install updates on the server to keep everything running smoothly, and usually this means that the site is unavailable for a short while. It's not usually cause for alarm, but you can always email us to ask and we'd be happy to let you know what's going on.
Now, get out there and create those new ambigrams!
