Next Challenge hint!

I normally don't want to share anything about the next challenge with you guys but since you guys have been waiting very patiently, I figured I'd give you all a very obvious 'hint' as to what it is :3
this is the image for the next layout, and if you hadn't guessed, its a collab between me and Fox ^^ the theme is for you to try and decipher :3

this next challenge calls for a lot of planning on our part so please bear with us! ^^
