There is a design that I have been creating on every TI I have owned since the TI-80 using the circle command that I cannot seem to get to work on the TI-84 Plus CE. The gist is to draw circles with a radius of R*sqrt(2) for all R from 1 to 30 or 40. It creates a nice circular fractal pattern. I started doing it back in the 90s when I was bored in Algebra 2. Then I moved to creating a program to draw it for me.

There is some window manipulation that must happen, but the heart of the program is this:

```
For(R,1,40,1)
Circle(0,0,R*sqrt(2) )
End
```

The problem I have with the TI-84 Plus CE is that there is this new concept of circle thickness that I am not sure how to change programatically. When I manually draw a circle, there is a new Style tab bound to the graph button. The default is a thick circle, which obscures the fractal pattern. I can manually change it to thin, and the fractal pattern is created. However, I cannot seem to figure out how to make the program draw with a thin circle. I have tried the Thin and dot-Thin commands both inside and prior to the loop, but it always draws a thick circle.

Does anyone know how to force the calculator to draw a thin circle?
