After our induction workshop we started designing our plinth to include the mirror grid on it. Our first idea was to attach the grid on the plinth surface, but it wouldn’t be stable enough to allow mirror manipulation. Thus, our plinth should have a higher front part where the grid will be included. This was our first design drawings:

Our initial idea was to get a neater front panel with a squared hole for the grid. However, we needed to test projection distances before starting, so we decided to speed up the process making the plinth in two parts. In that way, some of us could started to work on the base while the others were checking the distances.
It was here, when ere we had to face a problem. With the room we were given, the projected image on the wall was smaller than we thought whereas the reflected image on the grid remained bigger. To make they match we tried to gain as much distance as we can placing the projector 1 just over the grid and keeping the projector 2 on the plinth surface (figure 2).

Even doing that, the reflected image seems to be too big, so we decided that one option could be use only part of the 5x5 grid. The 3x3 grid in the middle seemed to work with the distances we had. So with a little bit of frustration we keep this option as a possible solution pending the final placement of elements in the gallery.
