But back to dimensions, 1200mm x 2400mm is much smaller than what I was expecting! Thank goodness I didn't continue with the bus shelter idea, clearly impossible. Though my IKEA rails aren't necessarily the perfect prototype and barely work anyways, their size is too large for the space given anyways.
This is when the creativity sinks in. Bigger clearly isn't always better. Shrinking works down could come to an advantage, I was thinking before in large scale - because I normally do - but now is a challenge to create a more intimate exhibit.
On another note, I have created various poster designs. Not all of them are brilliant, but the intent is to play with ideas. They are now in my mind, they can easily be modified - and will have to be modified once my railing system is figured out.
