Seed is a soothing, botany-based diversion that lets you cross-breed several different kinds of flowers into pretty mutant hyper-flowers. Simply select a flower species from the menu and it will spawn into one of five available locations in the dirt. Click on your creation to clone it, or click-drag and drop on another flower to crossbreed. Doing so will spawn a third flower into an available spot in the dirt. To delete a flower, hold [shift] and click on it. You may have five flowers only onscreen at a time, so additional crossbreeding or cloning when all spots are occupied will cause one flower to be deleted at random — so clone your favorite creations often. As an alternative, you can just let evolution decide all of this for you; this option gets very interesting if you have several species of flower in play.
Of course, it wouldn't be much of a game if you couldn't share your creation with others. Just drag your flower into a box in the upper right-hand corner to see its "DNA," the code you can copy and paste for others to view. I've seen some very interesting creations from simply crossbreeding the same species over and over again — so experiment freely and see what appears!
Analysis: Seed is a small game, but it'll keep you engaged for a while, particularly if you share your discoveries with others and try out their creations, too. Challenge yourself to create the largest, smallest, or most colorful flower you can. Right now the options are limited as there are about nine initial flowers, but the author has indicated he may add more later. For the moment, it's an intriguing little webtoy.
