Really funky, this, and really simple. You will need some unusual ingredients for this tutorial, mind.

Desiderata:

* Plasticard sheet (0.5mm is what I'm using)
* Plasticard tube: you want two diameters, one of which will slip inside the other. I used 5.5mm (7/32") and 7.1mm  (9/32")
* Sharp knife
* Polystyrene cement
* Superglue gel
* Embossed plasticard sheet (I used 1:50 treadplate)
* Aluminium car body repair mesh (this stuff is great. Buy loads of it. It'll be in future tutorials)
* Ruler
* Pencil

1) Cut yourself some sheets of 0.5mm-thick plasticard. You'll want at least two. They should measure 6" by 1.5". Leave a border of 1/4" (c.6mm) around the edges. Sub-divide the 6" strip into four 1.5" segments. Cut four holes of 1" by 1 1/8" in the two plasticard sheets. Cut a 1" by 5 3/4" strip of the aluminium mesh. See Figs. 1 & 2.

2) Use the oblongs you cut out of the 0.5mm-thick plasticard sheet to create a 1/8" border. Glue the aluminium mesh in place with the superglue gel, and glue the other layer of plasticard over this. Decorate it with a few bits and bobs, if you like. See Fig. 3.

3) Cut four more 0.5mm-thick and 6"-long bits of plasticard. Glue them together. Cut a 1"wide by 4" long strip of the embossed treadplate plasticard. Cut it into 4 squares with a side of 1". Cut twelve pieces of the thicker plasticard tube. Glue them as shown in Fig. 4: one at each corner, and two halfway along the 6" strips of plasticard sheet.

4) Get the thinner plasticard tube, and cut some 2" pieces. Make them taller or shorter if you like, but make them consistent. When you are absolutely sure that the wider-pieces don't have any wet polystyrene cement in them, you can insert the narrower tubes. Congratulations, you just made a multi-level walkway. See Figs. 5 & 6.

These multi-level walkways offer some nice 3-D options for your gaming(see Fig. 7). Would you like your Terminator squad to be able to blast Genestealers through the floor? You got it, Brother Sergeant. Want your Genestealers to be able to outflank those pesky Termies in three whole dimensions? From above and below as well as the left and the right? You got it, Broodlord. Just to reassure you folks, this aluminium mesh is reasonably strong stuff. So do not worry about placing a wee 28mm-tall pewter model on it. After all, it's designed to repair the bodies of cars! Until next time, folks, good luck iin your gaming!
