Introducing the PFx Brick. A device which transforms LEGO® creations with awesome new possibilities for lighting and, for the first time, sound! All of these features are simple to use and customized by you. The PFx Brick is currently a mature pre-production prototype product. Please support our Kickstarter campaign aimed at putting the PFx Brick into mass production. We are excited to finally share the result of many hours of intense and rewarding engineering design and development that we have invested into the PFx Brick!
