Kaleidoscope
Painter

Wait until the applet loads, then click the applet's canvas.  Move the mouse around the canvas while the mouse button is pressed (this is called "dragging" the mouse). 
Hint: drag slowly to create smoother drawing.
(Please note: applet requires a Java™ enabled browser. What is Java?) 

Clear Button...				Clears the canvas.
Auto Button...				Lets the program draw by itself.
DynaBrush Button...				Causes brush size to change dynamically.
Brush Size Panel...				Click the left-arrow to shrink brush. Click the right-arrow to enlarge brush.
Printing/Saving...				Unfortunately there is no easy way to save or print the picture.   However, you can capture the screen and save your picture as a bitmap file using the following steps.  Windows 95/98: * Make sure the canvas is fully visible on the screen. * Press the Print Screen (PrtScn) key on the keyboard (it's usually located next to the F12 key). * Run a paint program.  (For example, Windows has a paint program called Windows Paint.  It is available in Start->Programs->Accessories->Paint.) * Within the paint program, paste the picture, by selecting Edit->Paste.   * Within the paint program, you can print, crop, or save (File->SaveAs) the picture as a bitmap file.  Mac OS 7.5 or newer: * Make sure the canvas is fully visible on the screen. * Press SHIFT, COMMAND, and 3 at the same time. (e.q.: first hold down the SHIFT and COMMAND keys, then press the 3 key).  This will save the screen into a PICT file.  * Depending on the version of your Mac OS, the PICT file may be saved in the desktop or on the top folder of the hard drive.  Look for a file named PICTUREn (where n is a number and the last screen capture has the largest n).  * Open the PICT file using a paint program or by double clicking it. * Within the paint program, you can print, crop, or save the picture as a bitmap file.
