Check out these warning decals and the shock sign which I have posted in the Technical Reference section under the subject heading of: A Little Humor
I hope they are not in bad taste, or offend anyone. They are meant to bring a smile to your face only.
If you want to use the shock sign, feel free to download it and make hardcopies. The warning decals are from a Pad Mounted Utility Transformer, so is it a public domain image?
Next image to get [and make into a clipart item] is the "Kaos" Icon from Get Smart.
Anyone have leads to this??? Plan to try a digital capture from video tape to a PC [ATI All In Wonder card], but other ideas are helpful.
