Lexus commissioned a fully functional electric car built from laser cut cardboard. It comprises 1700 individual pieces and took 3 months, I imagine the builders were quite card-bored by the end of assembly.
Another post from the laser cutting group now, Jocelyn has shared these Christmas letters and is currently working to complete the set. I hadn't realised how early people start working towards Christmas craft faires until I started reading these groups but I guess it makes sense. I'll keep you posted as to when the rest of the set it released assuming they letter do it amidst all the requests.
Instructables user JackCarter made this awesome lasercut tank model from MDF. The functional tracks looks great and the laser is perfect for making a repetitive object like that, although they do also provide the files to make a static track if you don't have enough patience for assembly. There are lots of tank models out there but, because this comes with instructions, it is definitely a challenger for the best.
This laser cut ball mask from instructables user woz.artur would make a great costume for any Halloween event. The mask is cut from black acrylic and engraved with the maze detailing. The mask was heated and shaped to match the contours of a face and then the lines were filled with gold paint. The handformed nature to convert this from a flat sheet means you won't be going in to mask production but it would be a spectacular one off
