WordBulb is a playground for words. It started with a simple word cloud generator, but I kept building little things around the same idea — what else can you do with a bunch of words? Today you can create word clouds, make interactive word search puzzles, hide secret messages inside puzzles, play mystery-style word games, and explore collections built around different topics. Some are useful, some educational, and some are just fun :) Most of the tools are free and work right in the browser.
