My Year 9 maths students are currently learning the basics about Parabolas for the first time, and so they will need an online 24x7 online web-based Help site.
Good old "Wall Wisher" to the rescue, and we built the whole wall in one session, and did not move many post it notes around. This resulted in no problems or glitches whatsoever, and so this approach is definitely the one to use when building walls.
If you would like to view the above wall full size, then click on this link:

Note that we had previously done all our Internet research and had all the links and items we wanted to put onto the wall in a notepad text file.
However, we did have difficulty getting images to make themselves as zoomable post-its. Even though we built a practice test wall, where the images would display, when it came to building the real wall, they would suddenly decide not to display. It took a lot of fiddling around to get as many colour zoomable images as we now have on the wall to be visible.
So that's about it, parabolas are definitely my favourite shape, especially salt water ones like this classic "Rip Curl" beauty:
Enjoy,
