There is one more story about Cubicus (TW/RC). When designed, the expectations were that the Computing Centre of the building would be filled with mainframe computers. Hence, that part was over-dimensioned to accommodate for future expansion. However, with developments as they were (computers getting better and smaller), large spaces remained unused. Sometimes, these empty spaces would be used for exams. In June or August, this could be quite tricky. It could be hot weather outside like 30 degrees and you'd get into a room that was kept at about 16 degrees (as they were designed for computers, not humans). Many a student found out that sitting still for about 3½ hours in shorts and T-shirt was not very comfy!
One great untold story: I remember that 10x10 meter artwork by Cubicus (the old TW/RC) building. The idea of the artwork was that it would surface and then sink at random times. It worked a couple of times never to be seen again. Some years later a discussion started about what to do about it. The most original idea was to tie the artist to the artwork and let him surface and sink at random times...
And one more perhaps little known one: In the building was a large picture in Prof. W.J. Duijvenstijns office of the smallest simple perfect squared square of side 112 containing the smallest number of different squares (21) something he had discovered and proved to be the minimum.This squared square forms the logo of the Trinity Mathematical Society. It is also appears on the cover of the Journal of Combinatorial Theory. That picture may still be in the building somewhere or maybe its at the bottom of the lake too :^).
