Developers who received the HVC-C gathered at FabCafe Shibuya for the "Open Fab Night Sensor Special"(above), Kaoru Nakamura (bottom-left) and Akira Hatsune (bottom-right) giving presentations. Moriuchi: 194 developers made 75 prototypes with the "Make your own prototype" campaign. I think uploading images of developers making applications which use the HVC-C before release had a large impact.
