First, Fractal.
In case you didn't know it, a fractal is a shape which has parts shaped like itself (yeah). <bo-RING!>What we have here is a so-call iterated function system, meaning that the figure is created in steps, applying the same rule each step (which is called an an "iteration") an infinite number of times.</bo-RING!>. Here's an animation showing how it's built.
Creating this map in Sandbox actually didn't take much work but that's because I've cheated. Instead of building it all iteration-by-iteration I went straight to making the smallest block I needed and then copied and pasted a lot going from the smallest to the largest.
Now for my second map, House, Too.
Somewhat of staple in computer game mapping, this is a Flat-Roofed House. It somewhat lacks in furniture but has a pool, a fireplace, wine in the storeroom, two storeys, a shield made into a bathroom light, some windows and a glass roof for the lighting effects. There's some pretty rough geometry outside, so beware!
