An ambigram, also sometimes known as an inversion, or flipscript, is a graphical figure that spells out one or more words not only as presented, but also in another direction or orientation (from Wikipedia).

Here follows 15 inspiring examples, with some further ambigram resources.

Aerosmith

John Langdon designed this logo for Aerosmith.

“Created to be a gift from Dan Brown to Stephen Tyler. I was able to retain the look of Aerosmith’s long-standing logo, while turning it into a rotational ambigram.”

John has written some great tips for those wanting to create their own ambigrams, and I’ve referenced his website in the resources below.

Wachovia

The following two logos, for NIN and ABBA, have ambigram-like qualities.

Nine Inch Nails

For the band Nine Inch Nails.

ABBA

Logo for the iconic band, ABBA.

NEW MAN

Logo for the French clothes manufacturer, NEW MAN, designed in 1969 (source) by Raymond Loewy. This was one of your favourite logos, featured here previously.

Blacksmith website. Thanks, Steve.

Society 27

The Society 27 ambigram is a personal project of Pavel Pavlov.

Truce Vodka

Not quite an ambigram, and I’m not sure what you’d call it, but I found it interesting nonetheless — for Truce Vodka, by Agency26, who also created the Balance ambigram shown previously.

Update: 09 August 2009
If you know who’s responsible for the Truce design, do let me know.

Update: 22 November 2009
I’ve been told it’s by Turner Duckworth. Thanks, Owen.

Travel

For those travel-loving logo designers out there, how about this ambigram travel mug?

It’s available from Flipscript, and reads ‘travel’.

Labyrinth

I found this beautiful ‘labyrinth’ design in the ambigram Flickr pool.

Logo for Ambigram

You’ll notice this one isn’t quite like the others. It’s a logo for the Ambigram advertising agency, created by Pentagram (more info onPentagram’s blog). I think they missed a trick by not actually allowing for logo rotation. Okay, so it may not have been as legible, but you only need to visit the Wikipedia page on ambigrams for an example of how effective it could’ve been.
