Sometimes, what moves us is not the whole photo, but a very small part of it. OneStamp helps you crop your photos into stamp-shaped images. With a simple frame, a familiar photo can take on a completely different feeling. You may begin to notice details that once went overlooked, and rediscover the emotions, textures, and stories hidden inside the image. Landscapes, plants, everyday objects, or even an unnoticed corner of daily life can all be reframed here and turned into a small stamp of your own. It is more than a simple crop. It is a different way to look at a photo. When you look closer, you may really start to see something different.

RayMol brings high-quality molecular visualization to macOS, iPad, and iPhone — built on the trusted PyMOL engine with a modern, native Metal renderer. Load a structure from a file or fetch any entry from the Protein Data Bank, then explore it with smooth, real-time graphics: • Representations — cartoon, sticks, spheres, surface, mesh, ribbon, dots, and labels. • Real-time quality — analytic ray-cast spheres and sticks, smooth tessellated cartoons, anti-aliasing, ambient occlusion, real-time shadows, and order-independent transparency. • Hardware ray tracing — on Apple-silicon GPUs, add ray-traced ambient occlusion and shadows live, and export crisp high-resolution images. • Themes — Classic, Paper, Sunset, or Dawn, or design your own with the live Theme Studio. • Sequence, selections, and measurements — a synced sequence viewer, named selections, and interactive distance/angle/dihedral tools. • Movies — build and export camera, scene, and state animations. • Scripting — the full PyMOL command interface for power users. RayMol runs entirely on your device. It collects no personal data and includes no tracking or ads.
