Here is a minidem from CyberRex, they asked me to upload it (pad0/7)

ZXNet echo conference «zx.spectrum»

From Andrew Savichev To All 21 February 1998


Hi, All!
I received an unusual letter with software via Relcom, here is an excerpt from it...
----
I sent you my new software. (In addition to the demo, he sent me a couple of games.
But I entered into correspondence with him to find out about them what is required of me
A.S. )
It is not very good, but this is my “first attempt at writing” in demo .
Before that, I wrote only systems.(?)
----

And this is the contents of one of the files from the "asteroid" package.

You see my new minidemo Asteroid it is my first work on
zone demomakers.

Now about what you can see there (I suspect there’s nothing to hear ;) )
It’s like a black-brown piece of 3D plate rotating in one direction around an axis,
the rotation speed is adjusted using the Q and A buttons.
That’s all!
Whoever is interested, download other parts.

Sincerely, Andrey Savichev/CGS
