I actually did just like you said. I changed the time on the clock from 800 to 1000 (it blinks every second then). IN Malkierian's video he had a t-clock transmitter linked to the clock, I simply added a second transmitter calling it blinker. Then I did the pixel set up on the cloth for the colon in the time. Works like a charm.
Some of my plug-ins failed and it caused basically a melt down. The world was no problem as I backup often. But the next thing was to find all of the plug-ins that crashed. Took me about 4 hours to get it all back together again.
On a better note I think I know the problem with the clock :) It's a stupid little issue that even I run into and did not think of. Will explain at the clock in the World.
