I have tried lots of book prompts with Nano Banana Pro. This one is about math.
Prompt: A 2x2 grid of 4 large mathematical symbols built as pop-up paper engineering on an opened book
[Top Left: The Integral (∫) as a towering paper archway, cut-paper strata, printed equations as microtext wallpaper]
[Top Right: The Sigma (Σ) as a folded paper museum with sharp origami cantilevers, shadow play, diagram callouts]
[Bottom Left: The Pi (π) as a pop-up classical gate in layered cardstock, weathered ink textures, tiny paper pedestrians]
[Bottom Right: The Klein bottle silhouette as an impossible pop-up sculpture, paper tabs and join lines visible, elegant paradox geometry]
Tabletop editorial lighting, shallow DOF, crisp paper fibers, bookbinding details, inked diagrams, swiss grid layout, hyper-clean miniature realism.
