I created this graphic using iDraw on an iPad in less than 30 minutes. IDraw costs only £6 and offers most of the features of Illustrator for a fraction of the cost. Not sure what Adobe are playing at app wise at the moment?
I created this design simply using the word 'up' then repeating and interlocking the shapes making a little patern. The inverted letters also make the word 'dn' which is an abbreviation of down and the opposite of up. See - I thought this through!
I have a fond attraction to two things in design - halftone dots and overlays. In this graphic I've combined the two, although the overprint here is just an optical illusion. The font is Gill Sans Bold.
