This is probably likely intended for a niche crowd, but for those who enjoy logic puzzles, and also are familiar with Nintendo's Picross DS, I've been in the process of recreating all the bosses from the 2D Legend of Zelda games in picross puzzle form.
For those unfamiliar, Picross (or Griddlers, or Glyphix, since Nintendo trademarked Picross) is a logic puzzle "picture crossword" where you are shown a blank grid of squares with numbers on two sides, and using logical methods, filling in the proper squares to result in a final picture being shown in the grid.
If you are familiar with the game, my puzzles are located here: HeroGlyphix.com - Select a Glyphix Puzzle
If you aren't familiar with how the puzzles work but are interested in learning, the site here would be a good place to start to get the idea.
