       | The impact of the various directions of the fan or pin.

       | So much variation in such a simple seeming base.

         | I agree that this is a true work of art. The variation and
         | attention to detail is delightful. I hope more people put
         | together and share stuff like this on HN.

       | A game has a goal. Here you are free to experiment without being

       | Remove the spike and the little fan bubbles glom onto on another.
       | Very cool. You can just wave the bubble wand around too...
       | 
       | This is very fun.
