I found it hard to vote just by saying "I like this design" for each one individually. Since we have a set of limited option, I'd rather compare and pick the ones I prefer in comparison of the others.

I helped Claude build a simple web app (static, local, oss) to make you choose among pairs, to progressively determine your personal preference.

It outputs your top 3, you can share the summary like this:

  Recto Verso Euro  
  My top euro banknote designs:  
   Design H  
   Design D
   Design B

It's very WIP, but I found this approach useful to fill the survey, so why not share
