<b>Check your understanding</b>: what would happen if you moved the <code>self.wall.draw()</code> to inside the inner <code>for</code> loop, just under <code>self.wall.set_pixel(x, y, hsv)</code> in <code>SaturationTest</code>? (Try it!)
<b>Tip</b>: you can run individual tests by passing their names as command line arguments (argument -e or --effects) to <code>run.py</code>. For example, if you only wanted to run <code>SaturationTest</code>, you could:
<pre>python run.py SaturationTest</pre>▼
▲<pre>python run.py -e SaturationTest</pre>
=== 4. Implement a new effect called <code>RainbowTest</code> ===
Line 108 ⟶ 107:
Test your new effect with
<pre>python run.py -e RainbowTest</pre>
=== 5. Play with the randomness in <code>Twinkle</code> ===
Line 127 ⟶ 125:
<pre>
python run.py -e Twinkle
</pre>
Line 143 ⟶ 141:
<pre>
python run.py -e Checkerboards
</pre>
Line 161 ⟶ 159:
What other patterns can you create by tweaking the math for this effect?
===2. Matrix ===
Line 168 ⟶ 165:
<pre>
python run.py -e Matrix
</pre>
Each column that we see on the wall corresponds to a <code>Column</code> object. Add some randomness to the color used by each column (the variable whose value you changed above) using the <code>random.random</code> function, re-run the effect, and see what happens.
===3. Write more of your own effects! ===
