Check out the personal site of Seth Farris, who also goes by Typenerd. The design section of his site is extremely awesome, including the two images above.
Both images were created for projects related to Takeshi Murata, though for different events. The first image was for a video show he had, which was also an ice cream party. And I’m absolutely in love with the font in the second image! Click here to see the full size poster with more of those beautiful letters!
