The new Eastlink Freeway has some fun artwork included which make the journey less monotonous and also cute, and a tad creepy.
My two favourites are:
Public Art Strategy by Emily Floyd
A giant (and it is HUGE) blackbird looking at a geometric worm, little more to say really, but it's great - this is the cute one.
The creepy (in a good way) sculpture is Hotel by Callum Morton
It's a small scale hotel (probably equivalent to a real 2 or 3 storey building), but in a shrunken, Lilliputian style. You can see a metal staircase inside, but presumably there are no actual rooms (it's hard to tell, but I'd love to be able to go in and find out). The dark skies in this photo make it a bit more David Lynchian, and like all art it's in the eye of the beholder - some might find it amusing, but I found it to be attractively spooky and quite brilliant.
