地址栏也能打游戏！程序员用不到400行代码，在浏览器地址栏复活《贪吃蛇》，网友惊叹：怎么想出这个点子的？

Core Idea - The article discusses a creative project called "URL Snake," where a developer has implemented the classic game Snake within the browser's address bar using less than 400 lines of JavaScript code, showcasing innovative programming techniques and the potential for creative expression in unconventional spaces [2][4][12]. Technical Implementation - The game operates in a 40x4 pixel grid, utilizing Unicode Braille characters to represent the game elements, allowing for a unique visual experience despite the limitations of the address bar [10][12]. - The developer, Demian Ferreiro, used a method that involves continuously updating the address bar content to create the illusion of movement, similar to ASCII animations in command-line interfaces [13][21]. - The game supports controls via arrow keys or WASD, and as the player consumes food, the snake grows longer and the game speed increases, adding to the challenge [10][12]. User Experience - Players may notice that the browser's history gets filled with multiple entries of "URL Snake" due to the frequent updates to the address bar, which can be cumbersome to manage [14][16]. - The limited height of the game (only four lines) makes gameplay particularly challenging, as players must react quickly to avoid collisions [17]. Creative Exploration - Ferreiro emphasizes that the project is more about creativity and challenge rather than practicality, aiming to draw attention to the often-overlooked address bar as a space for creative expression [18][21]. - The project reflects a hacker spirit and a desire to explore the boundaries of what can be achieved in programming, encouraging others to think outside conventional frameworks [18][21]. Community Engagement - The project is open-source, with the developer inviting feedback and contributions from the community on GitHub, fostering collaboration and further innovation [11][19].
