Deskling
Deskling is a free macOS app that puts a small animated companion on your desktop. It wanders, naps and waves, and walks over to gently remind you to drink water, stretch and take breaks.

Tap Trail
TapTrail — You click through a site once while recording. Someone else opens the link and replays the path step by step: scroll, numbered marker, tooltip. It is a few kilobytes of steps, not a screen recording.
What Made You Smile Today
What Made You Smile Today? began with one simple thought: good things deserve a place to be shared too. After reading an inspiring article by a close friend, I wanted to share it more widely—but couldn’t find a space focused only on positive moments. So I built one.
OneScreen
OneScreen turns a laptop or projector into a shared wall: open a room, scan the QR, and photos, links, scribbles, and short messages appear on the big screen the moment someone sends them—no accounts, installs, or history.
Phone-as-a-Controller
Phone-as-a-Controller uses the same pattern for input instead of content: two to twenty phones join via QR and instantly become buzzers, votes, joysticks, or remotes for whatever is on screen, with no apps, pairing, or cables.
Scroll With Eye
Scroll-With-Eye turns your gaze into scrolling: look toward the edge of the page and it moves; double-blink on a section and that panel scrolls instead—including sideways when it overflows. The webcam stays in the browser, nothing is uploaded, and a click to start is all it takes.
Pass It
PassIt is AirDrop for reading position: press one key on your laptop, scan the QR with your phone, and the same page opens at the same paragraph with the same highlight—scan again on another computer and pick up there. The handoff lives entirely in the link fragment, so there is no server, no account, and no sync; a bookmark saves an address, PassIt moves where you left off.
