Team BttF will soon have their third Back to the Future based project reach 10,000 supporters. The "Jules Verne" Train is based on the time traveling train seen at the end of the trilogy and it will be the first train design of any sort to reach 10,000.
This will be evaluated with the Lego Birds and Modular Apple Store in the review starting on May 5th. Ideally we will receive a production decision in early September, if Cuusoo sticks to its target goals.
The Back to the Future theme has recently gotten an injection of fresh blood with AFOL favorite Orion Pax coming to Cuusoo. He has already uploaded several projects including a range of models based on "2015."
