REBOL [ File: %demo.r Date: 3-sep-2009 Title: "Demo" Author: Nick Antonaccio Purpose: { Amazingly small REBOL demo app: 10 useful programs in only 2.5k (LESS THAN HALF A PRINTED PAGE OF CODE!): 1 - FREEHAND PAINT: draw and save graphic images 2 - SNAKE GAME: eat food, avoid hitting the walls and yourself 3 - TILE PUZZLE, "15": arrange the tiles into alphabetical order 4 - CALENDAR: save and view events for any date 5 - VIDEO: live webcam video viewer - not just static images 6 - IPs: display your LAN and WAN IP addresses 7 - EMAIL: read emails from any pop account 8 - COUNT DAYS: count the days between 2 selected dates 9 - PLAY SOUNDS: Browse your computer for wave files to play 10 - FTP TOOL: web site editor (browse folders on your server, click files to edit and save changes back to the server, create and edit new files etc.) This example is 100% native REBOL. No external libraries, images, GUI components, or other resources of any kind are imported. It runs on Windows, Mac, Linux, and any other OS supported by REBOL/View.
