Sine Scrollers?




Wibbly-Wobbly-Scrolling

I've always had a thing for sinus scrollers! I mean, just look at it. Gorgeous!! This screen is called The Two-Screens-Together Demo by Black Byte/Bytechangers and weighs in at 3.5Kb - less than JetPac!! But why so tiny? Well, it was programmed for the first-ever STNICCC in their "VIC Times Revisited" competition. I guess, the rules were obvious with a Ram limit based on the Commodore VIC-20. Impressive results!!

Sadly, there's no music but I guess there wasn't enough space left over, which is completely understandable. I would love to see this updated with music and freed from the shackles of that old competition because it's too good to remain as is. I'm sure something beautiful could be done with this piece of code?

I'm always on the lookout for demos with similar scrollers but I fail to remember which disks I saw back in my youth. So it's been a painful process manually hunting them down. Of course, similar effects are used in many demos for waves, circle scrollers, distorting images, etc/etc... but I'm specifically referring to a sine wave used for a horizontal text scroller - like the one displayed above in all its wavey sexiness.

There must be a ton of cracktros and demo screens that I've forgotten about!! So, if you know of any using this sine scrolling technique, then please let me know in the comments below. Until then, here is a selection of text scrollers using the sinus effects which are all utterly amazing and definitely worth downloading...



Possibly the best-known ST sine scroller I'd say? Okay, there's no sound but the visual effect is great and incredibly well coded. I wish more would have been done but there's no denying how cool this is.

Circle Dots by MJJ Prod

This is such a smooth screen and with gorgeous music by Dma-Sc. The scroller is sine-tastic and works well with the stark palette style which really appeals to me. Oh, and there are some dots too which ain't too bad!

Sinfull Sinuses by Chronicle

What a great demo this is with a bunch of cool visual fx and great music. The sinus parts are very good throughout but this is all about the sinus text so I loved their big blue sine scroller, which is just lovely.


Another fine sine example and taken from one of the best megademos there is - Just Buggin'

Disk #0052 by BITS

A slap-bang, in-your-face, no-frills sinus scroller and it's pretty darn excellent too!!

Flexiscroll by The Resistance

An awesome screen from the Decade Demo but it spends (most) of its time doing everything other than what I wanted to see! However, as a demo, it's pretty cool with some lovely fx and wonderful chip music.

Genesys by Aenigmatica

Yes, it's quite mild but the sine scrolling is there and I like it. This is a pretty great demo too.

Menu #3 by Electronic

I don't remember this group from back in the day but here's an intro with a nice sine-scroller. Sadly, there appear to be many of their disks that still need to be found and preserved. Can you help?


An intro for a cool MOD disk that includes (possibly) the best player available for the Atari STe? Well, I was blown away by it! Anyhow, this intro has a dodgy image, cool music, and a neat sinewave to enjoy.

Arsch Screen by FOXX

This was released as part of Phaleon's GigaDemo and boy what a screen from an outstanding megademo. Nothing short of mind-blowing. Yes, both the sine scroller and the megademo. What a point in time this was!!

Alvin Puzzles Cracktro by Elite & STAX

This cracktro was used many times because it's fast, classy, and superb. I only wish the sine scroller had a splash (ahem) colour! One of my favourite intros for the ST. Erm, cracktro I meant to say.

Mr Heli Cracktro by The Replicants

The Replicants released what seemed like a zillion hacks and I've found a fantastic sine-scroller disk!!


The Anomaly Megademo is an absolute cracker and this screen is simply divine. Outstanding. [link]

Phototro by Hemoroids

This is a superb demo with a great plasma screen but the sine scroller is also pretty darn cool.
