Patent attributes
According to an example aspect of the present invention, there is provided for an apparatus comprising a User Interface, UI, the method comprising generating or receiving particles, wherein each particle has a first position associated with a first shape, and storing the first positions as current positions, determining a second shape, wherein the second shape forms a first target shape for a first transition from the first shape, and a first target time for the first transition, generating and storing first target positions of the particles associated with the second shape, comparing the first target time to a current time, responsive to the first target time being larger than the current time, determining intermediate positions of the particles, based on the current positions and the first target positions of the particles, wherein the intermediate positions are closer to the target positions than the current positions and updating the user interface by using the intermediate positions of the particles to provide a graphical output on a display, storing the intermediate positions as the current positions.
