This is a design that I came up a long time ago and I have just been sitting on it. I want to start producing it either as a t-shirt, pin, or actual wall clock. I think it could be a good seller at Spencer's and/or Hot Topic. The beauty is in the simplicity. This is the only cannabis novelty clock that uses this design.
Here's my original video explaining the function of the clock back in August of 2010..
Thanks for looking!
