A couple of weeks ago I compiled a list of 12 typefaces for 2012 which you can check out over at http://linefeed.me/. No.12 was a curious, custom made typeface created by French graphic design studio Helmo. Created for exclusive use by the newly extended and reopened, Paris-based contemporary art 'palace', the Palais De Tokyo.
The idea behind the typeface is quite simple, a series of 'punch-cut' holes line up to make letterforms. Through Helmo's execution, this simple idea has been splintered into a typographically-led identity system with seemingly infinite varieties.
The Palais de Tokyo's inhouse magazine, suitably named 'Palais', is a good starting point if you want to investigate Helmo's distinctly non-linear approach. Here you can check out how the 'Palais' typeface gently degrades as letterforms 9 dots high are stripped back to only 4 dots high and then mixed together.
Other tricks employed include adding 'outlines' to the letterforms to create a 'bumpy' effect similar to Julia's 'Riso' typeface developed for The Invisable Dot. The dots that make up the letterforms are also altered in shape and size or even filled with patterns and similar motifs.
