The Mishkan, in glorious description of its architecture - what it means to turn the inherently abstract words into a concrete physical structure. Constructing a visualization from the text - some people are exceptional at this, of course But what if you're not a visual person? There are different ways of thinking, of course. Plus: Making the attempt to "translate" the words of one section of the daf into more of a visual description.... How the curtains adorn the Mishkan. Part if what's tricky is being sure we know what each term means to begin it, of course. The visual then helps explain function, in this case, of the curtains. Also, consider the scope on the text and the capacity for interpretation that is expected of Bnei Yisrael, on building the Mishkan, as per God's description.
