→"Cross Hatch"
To go back to the PAT TERNS selection list to choose a different pattern, press '''ENTER'''.
==="Random Walk"===
Press '''3''' for "Random Walk." The cursor moves across the screen developing a graphic design as it travels. The direction of the cursor and the length of each line are selected by the computer at random. You hear tones that are determined by the direction in which the cursor is moving. The design generated in this activity develops on the "canvas" formed by the borders at the top and bottom of the screen.
The computer will continue to move the cursor at random until it has utilized all of the special memory space available. At that point, a blank screen appears, and a new "Random Walk" begins. In this activity, you can easily visualize the "wrap-around" nature of the screen. Notice that when a line is drawn to the edge of the drawing area it comes back on the screen on the opposite side. Thus if a line is drawn to the top edge, it reappears from the bottom of the screen. This occurs in
all of the activities.
Throughout this activity, you can change the colors you see on the screen. To change the color of the pen or the background, use the '''CHG''' (change) key sequence:
{|
|-
| Press || '''CHG'''
|-
| then press || present color key
|-
| then press || desired color key
|}
When you are ready to see a new pattern, press '''ENTER''' to return to the PATTERNS selection screen.
==="Cycle Thur All"===
Press '''4''' if you want the computer to go through all of the patterns one after another. The patterns will continue to cycle at random until you press '''ENTER''' to return to the PATTERNS selection list.
If you are looking at the PATTERNS selection list and want to return to the module's main selection list, press '''0''' or '''ENTER'''.
