  This paper presents a modular approach to enhance the capabilities and
features of a visualization and teaching room using software. This approach was
applied to a room with a large, high resolution (7680$\times$4320 pixels),
tiled screen of 13 $\times$ 7.5 feet as its main display, and with a variety of
audio and video inputs, connected over a network. Many of the techniques
described are possible because of a software-enhanced setup, utilizing existing
hardware and a collection of mostly open-source tools, allowing to perform
collaborative, high-resolution visualizations as well as broadcasting and
recording workshops and lectures. The software approach is flexible and allows
one to add functionality without changing the hardware.
