Automatic cursor mover

Could someone recommend a reliable automatic cursor mover software that would enable me to stay not-AFK in Voobly game room? It sometimes takes so long to get a game that I don't want to sit at my PC while waiting but I also don't want to go AFK because then nobody will join the room ever.

Or do you know of any other way to keep your account awake while not hanging out in Voobly room?
