LOL, CSpace is not being developed to display buses or fake imagery like 3D goggle technologies. There are different uses and applications that will make it valuable if they can get funding to mature the technology. CSpace, no matter how big the image space gets will enable the viewer to zoom in and out. This would be beneficial for displaying 3D data like medical imaging, baggage scanning, etc.
You keep comparing these technologies like they are competing with one another. They are not in competition and doubtful that they ever will be. They are completely different technologies and each will have its own strengths and obvious limitations. I prefer to see glasses/goggle free 3D dispays make it big someday.
