The Butterfly Ball and the Grasshopper's Feast is a 70's concept album / rock opera by Deep Purple's Roger Glover. The music video to Love Is All, featuring a lute playing frog in a cape, must be one of the best videos ever made. At least, I believe so.
When working on this font, the song popped up in my head (it is still there), so I decided to name this cute, cartoonish font after the album.
Butterfly Ball is a fun and happy typeface with rounded glyphs and an uneven baseline. Of course it comes with a hallucinatory range of diacritics.
