Petri Dish Cells Vector QR Code for Stickers

About this design

A round petri dish filled with glossy red, yellow, green and purple cell shapes on a pale blue ground, each outlined in white like a die-cut sticker. Three square cell clusters with ringed nuclei stand in for the finder squares, while the scattered blobs and small dots carry the modules. Dark blue and purple shapes against light blue and white outlines keep the pattern distinct. Tiny bubbles and specks around the rim add a lab-slide feel.
