Exolon!

Yeah! This is what Exolon is remembered for.
actually.. i couldn't figure out calculus of a simple sinus wave (like the defjam snurkel scroller) so I had to do it the other way around (integrating a list of handmade angular increments) which was probably good because the scroll became so much more crazy :)
Awesome scrolle ... especially for its time.
Its really an astonishing pie!
Very smooth snurkles, nice coding. Love this one. :)
yay :)
Amazing scroller here!
Quite impressive scroller. Not a plane, not a bird just a very nice piece of code.
Cool scroller :)
Cool scroller, cool tune (mod.disk maskin)
rocks of course. congrats exolon
love it!
Actually quite impressive! The rotating scroller is great, but the added highlights and shadowed edges are also pretty great, because they are added to the final image somehow rather than being baked in to the rotated sprites.
Best snurkler ever because of the crazy and never seen before moves.
Light maybe added by moving bitplane but I dunno. Great still.
I usually do not thumb up such screens but this time I couldn't resist due to that scroll.
I wonder about coding side, how the font is done, is it precalculated for every angle? if so, for how many angles and how big (kB) font data is.

No question, Exolon is a bright spark but I'll eat my hat if the char
rotation is in realtime.
I would roughly guess that one pre-rotated set of chars is about 4kb
and the stepwidth is maybe 6deg or someting like that which would
sum up to (360:6*4=) 240kb.
P.S.: On the other hand, it is an interesting and challenging thought
to pull off the char rotation in realtime. Maybe one could make use of
textured Blitter lines (catchword: $dff072). A one-pixel sine scroll
with 15px-high font seems to be doable with textured lines in one
frame - though it's a rather unconventional but also creative
approach for a sine scroll. But a "snurkler" is more complex. I think it
could be feasible but quite a job and the 64.000 dollar question
would be "How many chars can be processed and brought to the
screen in one frame?".
But maybe I am wide off the mark (I am not an Exolon :-) ) and
someone else can help and put his / her / it oar in?!

Loved it, still do.

Font data is of course precalculated and has a size of 138.240 bytes (320 pixel wide 2 bitplanes bitmap, 16 pixel height characters, 28 characters in font + 2 "empty characters" for padding, 36 rotation steps = 40*48*36*2 -> 138.240 Bytes).
ok, thanks
Forgotten thumb for cool old scroller, quite nice Fairlight logo and wild tune.
Woah! Probably the most versatile scroller I've seen. Khronos should make an OpenSCRL API for it!
It was fun to read!
Just great!
Excellent for that year
