SketchUp - 3D modeling for everyone! This is a downloadable program, compatible on both PC and Mac. I used this tool to create a blueprint/design of my current classroom, to envision changes that I would like to make. + TONS of furniture and choices from the 3D warehouse + The online tutorials are extremely helpful - There is a cost after the free trial - You definitely need a mouse to make it easier, so make sure you have one handy
From the flicker post, "The Lomo wall is complete! I've finally finished it! I proudly hung it on my wall last night; all six metres of it. It took a lot of organising, mounting and cutting but it's been worth it. Everytime I enter my house this is what I am greeted with : )"
