This was the logo and iconography for a 'Madness Sale' on Unity's marketplace for game assets. I started by looking for logos with 'madness' in them already but couldn't find any. So I started sketching first followed by type explorations in Roboto, Unity's font. This logo was created on a 10 hour flight from San Francisco to Dublin.
It didn't quite say 'Madness' enough so I played with the type more.
The font was too heavy so I used a light weight of Roboto
And here is the full set of promotional logos.
