If you're a fan of art - and who doesn't like a pretty picture? - it has been a rather spectacular week for our fair city.

The arty-farty fun began on Tuesday, with "Debris", the explosive solo exhibition of Portuguese artist Vhils, and ends today with the close of "the people's festival", HKwalls, a celebration of street art that has seen some of the world's leading practitioners battle the mist to decorate the grey buildings of Sham Shui Po with fantastic, in-yer-face murals. Meanwhile, along the Hong Kong Island harbourfront, the home-grown Art Central returned for its second year and the Asia Contemporary Art Show and Art Basel showed us stuff we couldn't afford.

With what can only be described as immaculate timing, TVB Pearl will round out the week-long celebration of creativity with the debut of Big Art (tonight, at 8pm), a six-part series dedicated to some of the largest works the world has ever seen.

Big Art follows the exploits of Urban Art Projects (UAP), a team of designers, foundrymen and installers who are in the business of making giant statements. This week, Sydney-based artist Nike Savvas attempts to create an optically dazzling sculpture suspended in a 10-storey light well.

Taking an in-depth look at the creative process, from conception through to design, creation and installation, Big Art documents each project through interviews and observational footage. But much like a fancy-pants Grand Designs, the highlight of each episode - and what we really want to see, of course - is the big reveal, and Savvas' colourful sculpture doesn't disappoint.

There's little doubt that to create some of these masterpieces you need more than just artistic flair; you also require access to a part of the brain that is off-limits to many of us. Maybe the odd narcotic or two has helped the world's greatest artists and musicians tap into this unknown, but would you be tempted to swallow a mysterious mind-altering pill if it unlocked all of your brain cells? Not the mere 10 per cent or whatever it takes to write this column; a smartdrug that could turn you into an intellectual superhero?

Much like 20-something slacker Brian Finch (Jake McDorman), the lead character in fast-paced new drama series Limitless, I think I'd give it a shot. What harm could it do? Well, quite a lot, as it turns out.

Based on the film of the same name starring Bradley Cooper and envisioned as a sequel, this week's frenetic pilot (TVB Pearl, Wednesday at 10.40pm) tells essentially the same story as the 2011 sci-fi thriller, paving the way for subsequent episodes to expand on the tale.

While our mopey hero Brian is drifting aimlessly through life, a friend encourages him to take a hit of designer drug NZT-48, which will not only alter his mind but change his life. Thanks to some great visual effects, the highs really do look like fun and after seeing the world in a brand new, super-duper light, Brian desperately goes in search of more of the good sh*t, only to find that his friend has gone and got himself murdered (ah, so there's the down-side!). Now the prime suspect, Brian manages to escape the FBI with the help of Special Agent Rebecca Harris (Jennifer Carpenter, the scene-stealing, foul-mouthed star of Dexter; above with McDorman), who is somehow convinced that he is not the killer.

Now Bri must harness the drug's power, with the help of US Senator Eddie Morra (Cooper, reprising his movie role), to clear his name and find the real baddie. Unfortunately, coming across as a sub-par cross between Sherlock and The Mentalist, Limitless only goes to prove that there is a limit to the fun you can have on a Wednesday night.
