Fun With Overhead Projector Sheets

I promised to send someone this particular table-top demo. So, I figured, put it on the blog then others can share in the elucidation and/or bewilderment. Also, I think I may release several of my other table-top demos that utilize “overhead projector sheets” or “write-on transparency film” — depending on where you go shopping. Which, by the way, Amazon has several varieties under $25 (for 100) and Staples has a couple types for under $25. There are $50-$80 transparencies out there. So be careful how you shop.

If you know me, and you are familiar with the Just Because Club or the “Any Game Cookbook” then what I’m about to say will come as no surprise: I am not going to tell you what this table-top demo will shop, prove, or demonstrate. Do the demo and find out for yourself.

Here’s the instructions.

1) Draw a maze (a simple maze) on a piece of paper.

2) Trace (as carefully as is reasonable) this maze onto 20 of the transparency sheets. Please use a proper pen that is made for transparencies — so that you can clean them later for reuse.

3) Go through the maze (using a color different from that one used to trace the maze).

4) Go through all 20 traced mazes.

5) Trace the maze onto 20 more of the transparency sheets.

6) Stack the first 20 completed mazes. Pay attention as you stack them. If you have a light table (or can mock up a light table) please use it.

7) Put the stack of “done” mazes to the side, and draw your way through the new mazes. As you finish each maze, place it on the existing stack — 20, 21, 22, 23, … This stack will grow to 40 as you continue. Draw, then stack, then draw, then stack.

If these instructions are not clear, ask. I can use your plea for clarification to help me improve the instructions.

If you have any question or comments (after doing the table-top demo) then ask. I will be happy to engage in a conversation about your results. However, if you ask me any questions about the demo before you have tried it, I will just suggest you try it. So you might as well do that to start with.
