The site coolhunter.com.au recently published a story about a launch that is a reminder that a really great idea doesn't need to cost a bundle to implement.
It could even cost as little as a few coloured packs of post-it notes.
"Hot on the heels of this fad, gaming giant Nintendo have promoted their latest baby Wii in Italy with this interesting wall display created by a series of posted notes. The post it notes make a nice 3D representation of a 2D pixel. "
Gee, that's a clever idea...I'm sure the agency charged a bundle for it, but what's to stop you coming up with your own version of this gem? Go on, get creative!
