REI's Minimap

REI's Minimap is an entirely client-side minimap mod made by Japanese mod author, ReiFNSK. It has a wide variety of features:
 * Waypoints (That cannot be teleported to)
 * Bump-map expression of height
 * Dynamically changing lighting
 * Automatic block coloring from the current selected texture/resourcepack
 * Biome colors
 * Map zooming
 * Ingame config
 * Zan's Minimap style minimap appearance option
 * Entities radar
 * Cave mapping
 * Indication of slime spawning chunks (Singleplayer only)

REI's Minimap was abandoned with only a beta build for Minecraft 1.7.2 on ReiFNSK's twitter, but an unofficial Forge patch has been made by Sedridor.
