For the fans...
Thank you all for the kind emails, rooting for the success of the project.
While the Kickstarter campaign to design my own iPhone app failed, I still would like to fulfill my obligation to those who supported this project. Thus, I will be releasing an Invisible Instruments program for Mac and PC that will work with an existing iPhone app "TouchOSC" available in the AppStore.
The software (includes the four basic instruments) will be released in a pay-what-you-can model, from free to however much you feel you can support.

There is a potential for an Android--Wiimote or an iPhone--iPhone computer-less design for a truly mobile instrument. However, I can't do it alone; after this, I'll be putting the project to rest lest any developers are interested in joining!
