Sample code 11-3 #24

The sample code 11-3 at page 222 doesn't work as expected.

Hi there! (just catching up on these...) Regarding sample 11-3, I've just tried it, and I want to make sure it's working for you.

When I run it as-is using the Exercise 11-3 link, it runs this circuit:

...and produces this state (looking just at the first 16 circles, all others are empty):

This matches the tile in row 3, column 2 in the sample output as shown in Figure 11-10:

By changing the tile position on lines 17 and 18 of the sample:

...you can get any other tile to render.

I do notice that in the book itself the specified tile is 2,1 instead of 2,3. Is this the problem you're pointing out?

In any case, if you can clarify the issue you're seeing I'll be happy to help fix it. Cheers, - ej

@machinelevel There's nothing wrong with this code, but one question remains: can it show the entire 16 by 16 image like the one in the book?
