Brenton Bock wants Hollywood-style sign for Adelaide in the Hills

NOW this is bold. Ad man Brenton Bock thinks Adelaide should have a Hollywood-style sign up in the Hills. That glows. Cue your response.

The proposed Hollywood-style sign as it could look from the city.

AD man Brenton Bock has a Hollywood-style vision to build a giant, glowing Adelaide sign for the Hills.

He thinks the interactive sign should be placed in a direct line to Rundle Mall and linked to the lantern on the corner of Rundle Street where people could trigger images or lighting on the letters in the distance.

"I would like to see people standing in the middle of Rundle Mall on New Year's Eve and to look up at the sign and see a laser light show," Mr Bock said.

He shared his idea at the ­recent opening of his company Blackbocks' new office space in Norwood, saying it could ­attract private investment.

"Considering everything we are investing in the town, the Brand SA thing is brilliant, but to be surrounded by the foothills as we have got, it's a unique offering," Mr Bock said.

"Am I getting the discussion going as a bit of a stir, possibly, but I think it's a great thing. Why do people have personalised number plates, why does my daughter have her name on the door?"

Mr Bock's three-year-old Blackbocks agency is in the midst of lifting its own profile with its move into the renovated St Mary's church building in Beulah Road.

It has also recently acquired new clients, including Monroe shock absorbers - owned by the global Tenneco group - and the House & Garden retail group.

A television advertisement the agency has made to promote the Fifty Shades of Grey party board game is also due to appear on both local television both locally and during the Ellen show in the US.

It was made for Adelaide company Imagination Games, after it won the rights to create the board game linked to the Fifty Shades of Grey book series, and was directed at a female market wanting to "discover your inner goddess".

Mr Bock worked in retail for 10 years before switching to the ad industry in 1989 and establishing his own agency three years ago that had been based on Fullarton Road.

The move to the new building was about creating a more creative workspace, Mr Bock said.

His new home had already created a local stir after winning Best Heritage Development, Best Commercial Development and the Brian Polomka Award for Most Outstanding Development in the Norwood, Payneham and St Peters' urban design awards last year.
