Acrylic is a great material to work with as an internal designer. it safer and more durable than glass (though tends to get scratched more) and can be manipulated with greater ease than glass. I found a lot of Idea of what could be done with acrylic in internal design at the plastic spork blog
for example the water wall Or this Acrilic Bar and lighting
with more cool pictures and ideas here
or even acrylic sliding doors
more about this project here.
definitely a good resource for anyone thinking of using acrylic.
