Equipment required:
-------------------
- IBM compatible PC, XT, AT with IBM compatible Color Graphics
Display Adapter and (preferably) a color display. Fantasy
writes directly to the graphics screen buffer for speed. It is
therefore not compatible with other display adapters such as
the Hercules standard.
- MicroSoft compatible mouse, with either MOUSE.SYS or MOUSE.COM
loaded. (Fantasy will run without the mouse, and you can cause
movement with the cursor keys -- but it just isn't the same.)
What is Fantasy?
----------------
- Quick summary: fantasy creates flowing graphic images on your
display as you move your mouse.
If art can be fleeting, transitory and personal -- then Fantasy is an
artist's tool, and you are the artist, and you are the audience.
Fantasy is a tool for personal performance art. Like building sand
castles or blowing bubbles, each performance is different and highly
personal.
Fantasy lets you control a variety of pleasing and sometimes hypnotic
images on you graphic display. As you move the mouse the image
constantly moves and responds in never-ending, never-repeating
animated sequences.
How to use Fantasy:
-------------------
Simply run FANTASY.EXE. An initial display will show a list of valid
commands and the keys used to evoke them.
To start the action press any key on your keyboard. Then move your
mouse and keep it moving slow and steady to get the idea. You should
see the initial square mouse cursor shape move in response to the
mouse, creating a snaking trail moving off the top of the display.
When you stop moving the mouse, animation stops. The idea is to
"conduct" the performance by constantly moving in small or large
sweeping curves.
You can re-display the initial help screen by pressing the [F1] key
(without moving the mouse).
Special effects
---------------
You turn on one of the special effects by pressing the key letter for
that effect. For example press [B] to start the Box effect.
The Box effect: press [B] to start the box effect. This causes a
square box to be drawn as the mouse is moved. Initially, the size of
the box is eight pixels. You can change this size by:
1. press [Esc] to end the current effect.
2. enter the new size using the number keys. For example
enter [48] to change the box size to 48 pixels.
3. return to the box effect by pressing [B].
The Rectangle effect: press [R] to start the rectangle effect. This
draws rectangles of varying size originating from the position of the
mouse cursor when the effect was started, moving to the new mouse
position as you move.
The Circle effect: press [C] to start the circle effect. This draws
circles of varying size with their center at the position of the
mouse cursor when the effect was started. Their diameter is changed
as you move the mouse.
The Line effect: press [L] to start the line effect. This draws a
sequence of lines starting from the position of the mouse cursor when
the effect was started, moving to the new mouse position as you move.
The Multi-Line effect: press [M] to start the Multi_line effect. This
is similar to the line effect, except that you can change the origin
point by pressing the mouse left button. Each time you press the left
button line drawing starts from that new position.
The Free lines: press [F] to start the Free lines effect. This draws
a short line (depending on how fast you move the mouse) that seems to
follow the mouse movement like a tail. This effect is most effective
with the mouse cursor off.
Switching Effects
-----------------
To end one effect and start a new one, press the [Esc] key, then
press the selection key for the new effect.
Another way to switch: press both mouse buttons to switch from one
effect to another in sequence without needing to exit. This allows a
more seamless transition from one effect to the next in your
performance. This method will not get you into the Multi-Line effect,
but if you start with the Multi-Line effect then press both mouse
buttons you will eventually return to it.
The mouse cursor
----------------
Turning off the mouse cursor: Some effects appear better with the
mouse cursor turned off. To turn it off:
1. press [Esc] to end the current effect.
2. press [F3] to turn the mouse cursor off.
You can turn the mouse cursor back on by repeating the above steps.
Changing the mouse cursor: there are currently three cursor shapes:
The initial square box cursor, a cross cursor and a diagonal cross
with arrows. You change to a new shape by:
1. press [Esc] to end the current effect.
2. press [F4] to turn the change to a new mouse cursor
shape.
Screen Color
------------
Fantasy uses the Color Graphics Adapter's high resolution mode of 640
by 200 pixels. In this mode the background is always black, but you
can change the foreground color to one of the 16 possible by either:
1. press the [F2] key, or
2. press the mouse right button.
The second method works while a special effect is on.
Ending Fantasy
--------------
1. press [Esc] to end the current effect.
2. press [F10] to exit and return to DOS.
Genesis of Fantasy
------------------
You may find it interesting: The fantasy program is the result of a
simple error made while debugging a new graphics program. This new
program called PC-Draft III is an object oriented CAD drafting
program which will be a similar to our PC-Draft II product which is a
pixel based drafting program. In the course of debugging, a trace
message inadvertently caused the graphics display to scroll each time
the cursor was moved. This caused effects similar to what you see
with Fantasy. We found ourselves delighted with some of the effects,
playing with them for hours. We have no idea whether this will have
the same impact on others, or whether this phenomenon is strictly
personal -- perhaps because it is our own programming effort.
