Lumino is a variation of the ancient found poem game, created as a gift for people who love to look at letters. In a labyrinth at night (a metaphor of our world, disordered and boundless), the only light comes from language itself. Capture poems as you navigate through this space, where you pick up fleeting words and transform them into unique poetry. How? - Tap to keep the words you like on the screen. - Shake your phone and a line of poetry will be composed using the selected words. - Scroll up, down, left, or right to explore the space, and create more lines of poetry. When you find the hidden word "infinity", tap to complete the found poem game and discover how your poems illuminate the path out of the labyrinth. ------------------------------------------------------ "I thought of a labyrinth of labyrinths..." - Jorge Luis Borges Within this literary labyrinth, you will find: - Cryptographic Seed: One of 2,048 BIP-39 seed phrase words awaits at the origin (0, 0). - Infinite Paths: Swipe in any direction to explore - up, down, left, or right. Lost? Keep moving; you'll always find your way back to the start. - Words as Light: Tap to capture flickering words, illuminating your path through the darkness. - Emergent Order: Shake your device to evoke order from chaos, transforming random words into meaningful verses. - Journey to Infinity: Each path leads to "infinity" - the mystical exit that completes your poem's trajectory. Note: Lumino was originally made for a conceptual exhibition "Poetic Cryptography" in the "Infinite Garden" of ETH Devcon Bangkok in Nov 2024.
