Watching the time pass has never been so beautiful! Gravity Clock visualizes the passage of time by the permanent destruction and reconstruction of the clock-face. Every second the hand breaks numbers out of the dial and lets them drop to the floor where they get buried by the following numbers and eventually wither away to make room for the endless succession of time.

Garno — the smart yarn calculator for knitting and crochet Garno is a simple yet powerful tool — made by a knitter, for knitters and crocheters. Got a pattern but not the recommended yarn? Garno helps you accurately recalculate how many meters or skeins of your yarn you’ll need when using a different yarn or knitting with a different gauge. How it works: 1. Enter the yarn from the pattern (meters per gram + gauge). 2. Enter the amount of yarn required in the original project. 3. Enter your yarn (meters per gram + your own gauge). Garno instantly calculates how many meters or skeins of your yarn you’ll need — based on real gauge, not rough estimates. Perfect for you when you want to: - confidently replace yarn, - know the exact amount of yarn needed, - avoid running out of yarn or overbuying. No login. No ads. Just clean, friendly math that speaks your crafting language. Garno turns the frustration of yarn math into something easy, fast, and reliable — so you can spend less time calculating and more time creating. Garno — smart math for creative makers.
