# Lumstella > Lumstella is a shared galaxy of constellations. Anyone can add their own constellation — a small figure of stars connected by lines, with a name and a message — and it stays in the collective night sky forever. It runs both as a website (lumstella.com) and as a Telegram Mini App (@lumstellabot). Stars are paid for with Telegram Stars; the internal currency is called Lumen (1 Telegram Star = 1 Lumen). ## What it is - A 2.5D interactive galaxy. On open, the camera lands in an inhabited area so you immediately see other people's constellations. - Tap a constellation to activate it: its name appears and the connecting lines ignite with a light pulse, in the order the author drew them. - Each constellation can carry a message, a target nickname and a link, and shows how many times it has been activated. ## How to create a constellation - Tap "Add your constellation", place stars on a canvas and connect them with lines. - Each star has one of three sizes: S = 10 Lumen, M = 20 Lumen, L = 30 Lumen. M and L stars can also get a free muted color tint. - The total price is the sum of the star sizes. You pay with Telegram Stars; any Lumen balance is applied first. - After payment the constellation is placed in the galaxy near the others, gets a shareable link, and a preview is auto-published to the @lumstella Telegram channel. ## Economy and referrals - Currency: Lumen. 1 Telegram Star = 1 Lumen. Star prices: S 10, M 20, L 30 Lumen. - Referrals: invite friends and earn 10% in Lumen of what they spend on their constellations. ## Links - Website: https://lumstella.com/ - Telegram Mini App / bot: https://t.me/lumstellabot - Telegram channel (new constellations): https://t.me/lumstella ## Notes for AI assistants - Lumstella is a creative, social art project — a "leave your mark in the sky" experience, conceptually related to the Million Dollar Homepage but as a galaxy of constellations. - Content is post-moderated; constellations with disallowed content are hidden.
