After a long silence some good news was posted on the VGTU project@Home website yesterday ...
Dear VGTU@Home users,
We would like to announce a new beginning of our project. We have finally managed to find and develop a true scientific application for our project. With your help, we hope to obtain interesting results!
With best regards,
The Project Team.
The application is called "VGTU@Home application for dynamic visual cryptography based on non-linear oscillations"
The server status page shows that some tasks are currently in progress, though none are ready to send at the moment - I haven't been able to get any yet.
