The logo shows three cherries with three leaves, which together form a flower. A kissing mouth forms in the middle. 
The claim serious fun work forms three characters matching the respective word.
If the logo has to be displayed smaller, the claim is no longer visible, which is why I tend to use this variant. If the logo can be displayed large, the variant with claim is used.
I created the lettering myself. It is not a font or anything like that. Maybe I will make the alphabet as a font. What do you think? 
MAKING OF VIDEO - from crappy drawing to a very nice logo.
