OpenSource Self-replicate 3d-printer

Future is coming. Guys from reprap.org build self-replicate 3d-printer.
The printer prints a 3D-object from plastic thread.

This RepRap printer will make the components using FDM Rapid Prototyping technology, which essentially builds the component up in layers of plastic. This technology already exists, but your cheapest setup would set you back £15,000. And it isn't even designed so that it can make itself! So what we, the RepRap team, are trying to do is to develop and give away the designs for a much cheaper (material costs will be about £300) setup with the novel capability of being able to make itself - so you can give one to a friend for Christmas.

Very comfy office chair bike

A recumbent bike with a very comfy seat. It's a 35 pount leather executive office chair connected to a 16" (little girl's) Princess bike re-welded into a recumbent (recliner bike) and using a piece of another donor bike frame. I built it in honor of "Bike to Work Day".
