So a bit of background first: the PC1512 included a planar extension to CGA, providing 640x200x16 colours. BASIC 2 provided dithered drawing of complex shapes.
LAKESIDE.BAS was a very early procedural graphics generator, using a random seed to draw a, by modern standards, primitive 2D scene. In the distance there was a sky with clouds, snow peaked mountains reflecting in a lake, with little islands and sail boats. In the foreground, there were hills, white buildings with red roofs, white picket fencing separating fields, and all sorts of flowers, bushes and trees. Given how slow the machine was, it'd take a minute or so to draw each picture, leave it up for a little while, and then draw another one.
Whilst this could undoubtedly be rendered in 3D in the blink of an eye, and all sorts of shader magic could make it look like an actual painting, I think it would lose some of the charm.
