A new page element runs Conway's Game of Life in an area (the whole display by default), one per page. Start: random dots, one pattern, or the icons whose names start with a text in turn or in random order. Edges: wrap around, dead, or a hidden margin where gliders fly out of view (leftovers that stay put in the margin are cleared, so a glider gun runs cleanly). It restarts when the board is still or repeats within 16 generations and/or after a number of generations, after a hold time (an empty board at once). logic/life holds the board and timing (tested), display/life_player runs the board of the shown page, ticked before each frame; frames are paced like scrolling text. The element reuses existing fields, so the page format stays the same. The Icons tab has a library of 17 LifeWiki patterns (checked with a simulation), and the built-in page "Game of Life" shuffles through the life_ icons. About 12 KB flash, 8 KB RAM. Version 2.17.0, tested on the display over OTA. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
