Vex Spore turns the mathematics of crystallographic symmetry into a live design canvas. Choose one of the seventeen wallpaper groups — every way a pattern can tile a flat plane — drag a single vertex on your motif, and every symmetric copy updates at frame rate. No render button. No waiting. The group enforces its own rules; you just move points. Place a polygon in the fundamental domain and the engine tiles the entire plane exactly: rotations, reflections, glide-reflections, and translation lattices all computed from first principles. A symmetry overlay draws rotation centres, mirror axes, and glide lines directly on the canvas so you can see the geometry you are working with. Four colouring modes — single, translation parity, handedness, and coset tint — let you explore how colour interacts with the symmetry of the chosen group. When your pattern is ready, the Repeat and Yardage scr…
Every shipping app on the App Store has gone through the same decisions you're working through right now: which screenshot goes first, what caption sits over it, which device frame to show, what color the background should be. The 10 screenshots above are Vex Spore's answers to those questions — they're public, they're real, and they made it through Apple's review.
What the numbers say: Vex Spore runs a mixed light-and-dark set where the background shifts from screenshot to screenshot (first shot #FCFCFC) — each image has to stand on its own, so the captions carry more of the story. The accent colour we picked up, #FCFC04, is the one to reuse for badges, arrows and highlighted words if you borrow this look. Hit Use this style to open the editor with these exact colours and drop your own screenshot in.
Notice the first screenshot in particular. It's the one users see in search results and on the product page, and it's where most apps spend their best caption and tightest design. Look at the proportion of background to phone, where the text sits, what one thing the image is trying to communicate.
