I have seen a physical version with LEDs and I loved it. It says Discovery Channel™ on it, so I assume it came from there. I liked it so much that I made one in Java™. It displays the time in six columns of four rows each. Each column represents a decimal digit, 0-9. Thus this display:
In case you've forgotten (or never knew) the binary numbers, here is a table of the binary numbers from zero to nine:
Unlike the above tables, if the applet is working properly, there should be no "borders" between the rows and columns. This zip file contains all the source, images, etc.
Here is the applet:
If the applet doesn't appear, you may need the java plugin, which is available from Sun (for free) at this location.
<applet code="com.palserv.clock.BinaryClockApplet.class" archive="clock.jar" width="300" height="200"> Your browser is completely ignoring the <APPLET> tag! </applet>The applet can also be "customized" using the param tag. The param names and what they mean are:
|background||color||the background color of each Bit.|
|foreground_zero||color||the color of the circle for a "zero" Bit.|
|foreground_one||color||the color of the circle for a "one" Bit.|
|outline||color||the color of the line around the circle.|
|height||integer||the height (in pixels) of each Bit.|
|width||integer||the width (in pixels) of each Bit.|
|radius||integer||the radius (in pixels) of the circle.|
<param name="background" value="255*0*0">For "integer" types, the value must be specified as a number. First, the size of the applet (which is controlled by the height and width attributes of the applet tag) should be related to the size of the Bits. There are four rows of six columns of Bit objects. If the applet size is too large, you may see some other color peeking out from around the edges of the Bit objects. If the applet size is too small, you may see some compression of the Bit images. You may have to play with the sizes to get the effect you want.
