Roy Block is installation that examines the interface as a transition between physical and virtual world. The installation features a self-willed heroine who is trying to get from the very left to the very right of the screen. However there is nothing she can stand and jump on so she needs the player to help her.
The player has two small blocks, in each hand one. Pressed on the screen they are being recognised by the game and the heroine can jump on them.
An integral part of the game is put into the player's hands and becomes the interface. This transformation leads to an almost seamless transition between physical and virtual challenge.
