synthesized reality productions ★
Synthesized Reality Productions is a group dedicated to putting on Vocaloid concerts around the world. Vocaloid is a singing synthesis program that has become widely popular thanks to the program's avatars - more information on that can be found here.
The group is made up of a bunch of talented and deeply devoted Vocaloid "producers" (that is, people who create songs and animations for Vocaloid). They no longer use this design for the site, but they appear to still be active.
