A rather old and probably broken version of Clockwork that TeslaCloud Studios (Luna, AleXXX_007 and others) used to maintain.
Original code was written by Conna Wiles, Alexander Grist-Hucker and Igor Radovanovic, with contributions from the Cloud Sixteen community, credits for which you may find in the original repository of Clockwork.
This code is probably broken. Use at your own risk.
