The computer that I had when I was at school in the 80s - in common with a
lot of personal computers at the time - allowed you to design your own text
character. You could use this in a game - e.g. to make a "space invader" -
or you could use the same technique to make your own font. I made my own
font that looked like my handwriting!
Characters were designed on an 8 x 8 grid, and created using eight numbers
from 0-255. Each number was converted to
binary and the resulting
pattern of 0s and 1s was used to make a pattern of black and white dots on a
You can design a character in the same way by entering numbers from 0-255 in
the boxes to the left of the grid. Each number is converted to
used to create the pattern of dots.
Fonts on a modern computer would be made up of a lot more than 64 pixels, but
the principle is the same.
If you can't see how the numbers are converted into the patterns of black and
white blocks, try looking at the page on
binary. If you
can see the link between the number and the pattern, then think about how the
web page works - maybe you could create something similar in a
