(Sacramento Bee) Sign-spinners – the people who gyrate on sidewalks to get your attention for businesses – have battled heat, wind, rain and cold for years. Now they face a new threat: machines.

“It runs 60 hours nonstop and doesn’t take any breaks,” said Velocity Signs President Scott Adams, pointing to a so-called “sign-waving machine.”

The machine – invented by the Sacramento company three years ago – has won accolades from local business owners who say the technology is a cost-effective alternative to hiring human sign-spinners.
