@Strigoii : Currently, I publish a series on the french site about french words which nearly nobody knows. This grid represents "pareidolia". But when I publish a hanjie on the english site, there isn't the same context. So I don't translate the french title, in order to find the "good" title. I especially like play on words, even if it's harder for me in English. For example, the french title of my grid "Pacha-cha" contained a better joke. Then, you're right, it's indeed a play on words ;) I'm glad that you noticed it.

Merci à vous pour vos chouettes commentaires plain de bons mots :)

Thank you for all your comments.
