Invisible grill

[mamapanda]

Hi,
Has anyone heard of invisible grill? I know it's available in Singapore but any contractor in HK does it? http://www.invisiblegrille.com.sg/
My hubby hates traditional window grills. But my 4-mo-old DS is already pretty active! I guess we'll need to install some eventually.
Any suggestions?

I am very interested in something like this too. Will ask around and see if anyone knows.
