Yesterday, I ran across a rather intriguing article in C Users Journal about
Gadgets.  The Author was Jim Fiore, and the program was called JustSayYes.c
For someone like myself who is learning how to program the Amiga, I enjoyed
this article.  He takes you through the process of building a color changer/
editor for a custom screen. You build 8 color selectors, 3 slider gadgets,
2 larger buttons, and an Amy 3000 in a pear tree.8^) The source code is 
about 12 pages long but reasonably commented.

Now for a different question:

I am wondering if anyone has built a dial gadget/slider. You know, like
on a combination lock.  A common experiment in Psychophysics is to give
a subject a frequency generator with an unmarked dial/knob and have them
turn the knob until whatever it changes matches whatever they are receiving
as a stimulus.  In my case, I have been thinking of a frequency generator and
using the Amiga to generate Audio stimuli to do pitch matching experiments.
A slider wouldn't work as well
as a knob, since the slider has a left and right end that would provide the
subject with some sort of reference to his/her last pitch match.

Well, just a thought.
