By Orig-ARM-I (now Reactive)
A fairly short one this, which seems to mainly involve eyes staring out of the screen at you...
There are some interesting effects: look out for the light sourced sphere bouncing around the screen, and the refractive one doing the same thing. However, this is a first effort - it shows - and the code creaks quite visibly in places: the image-rotation section notably, slows down very considerably at some angles but not at others, which shouldn't really happen in an FX demo particularly as it isn't a difficult problem to fix.
This isn't the cutting edge of Acorn demos, nor did Orig-ARM-I ever claim it was.

A single-effect demo, this jumps around a small plot of land in 3d, all super smooth with some very fast polygon plotting! It doesn't show off the StrongArm very much, but there is a multi-tasking version which runs in a window in the desktop while you're doing other things :-)
Kulture's entry to Revelation '97 is a short but very large (2Mb+) number running in full colour. It starts off with some nice title effects - the brilliant lighting on the "Freestyle" title comes out very well - and then runs into two main effects, firstly a rotating cube with coloured lighting, complete with a lens-flared light source behind it, then a strange-looking wireframe which spins around, leaving a slowly fading trail in its wake.
That's it - there's the credits sequence and then it's all over! For a demo with such a short running time Freestyle is massive, although the large full colour bitmaps probably take up much of this. Oh, and the music is really hot.
Pretty good, despite its shortness.

This was Quantum's production for the StrongArm CD - maybe not technically the best demo on it, but Icon's bitmap graphics are second only to Fluoro's (and much higher res) and although there isn't anything really remarkable, there are several nice effects on offer. A series of fading titles is followed by some images with dark bands moved across them, and faded together in the same manner; a few transitions, then a rather good light sourced 3d spreading thing (I forget what that's called, see the screenshot), a rotating, warping texture, and then the credits sequence. Not bad, although Icon doesn't show off the StrongArm as much as some of the other demos on that CD.
DFI's first proper demo: interesting, although it's a shame there isn't any music.
After the very nice watery opening sequence (it jerks a little in places but the effect isn't simple) watch of for the big stone chess-pieces, the towers reflected in water, a 3D voxelscape (well, a lot of grey tubes actually, but it's technically pretty good) and a nice gouraud-shaded texture map to end that you'll recognise if you've followed the Acorn User series on 3D engines.
July is technically good but I feel it is a little tacky in places - the chessmen "look" very angular and the viewpoint isn't that interesting (up-and-down movement would have added a lot to it). DFI will be a force to be reckoned with in the future though, I think.

Frederic Elisei has obviously spent a lot of time writing a really good light sourcing routine, and this demo certainly shows it off on a variety of objects. Many of the light sources or objects can be moved around manually using the mouse - just to prove it's all realtime! It's also in a high colour, high res display and very impressive.
After the light sourcing, there's also a "Plastic Pool" - an unusual water-type simulation - and a very good realtime Julia set. This is in high resolution and makes use of the StrongArm's high speed multiply instructions to great effect, making previous renderers look very slow! The demo ends with a fire effect spelling out the words "ARM'S TECH" all over the screen, and there's also a hidden section - no I won't give anything away!
It's a shame that this had to be put together to a strict deadline to make it onto the StrongArm CD-Rom because technically this is one of the best demos on the scene: if some transitional effects and music were added it would be stunning. It's still very good though, and there are lots of PD soundtrackers around now so you can add music yourself if you want to.

One of the first proper RiscPC demos - this flashes by all too fast on a StrongArm, although it's pretty good while it lasts...
The first effect is a (rather visually foreshortened) landscape which I have to say, reminds me more of fried eggs than anything else, although as the demo was released at the Fried Bits 3 demo party... There's also some bitmap graphics (in Gizmo's characteristic cartoony style), a water effect similar to many others, notably in Era, some spinning 3d objects, a dots section and a rather drawn-out although pretty good credits sequence.
The music is very odd! But altogether this is a good demo, although you get longer to see it on Arm610/710 machines!
By The Xperience
The Xperience's first proper production, and one of the best displays of how good Acorn's original ARM2 based machines were. This is a big demo and packs in lots of effects. There are quite a few moving-dots objects (including a ripples section made up of literally thousands of points); several 3D objects (look out for the novel twisting board near the start); a refracting sphere, the list goes on.
Presentation-wise, this isn't quite up to the standard of The Xperience's later demos - the restriction to 256 colours makes many of the images look a bit tacky, in particular. However, it all rolls by at a good speed even on the slowest machines, and certainly is proof that your old A310 isn't quite finished yet!
The music has appeared separately as a Digital Symphony tracker but I have a strong feeling this isn't such good quality as the original...
Despite rumours to the contrary Xcentric will run on any Acorn machine up to and including a StrongArm RiscPC if good use is made of a cache control utility, although it won't be very stable. The RiscPC mode def supplied isn't very good so I designed a better one for it, this works much better on my AKF60. It's 98Hz so the use of VSyncX2 or similar to slow the interrupt rate will stop the speed from going through the roof.

A class apart, this one. At 4.5Mb it's the biggest Acorn demo by a long way. Xtreme was created by lots of different people, and is basically loads of effects one after the other. A major fault in this demo is there's no linking whatsoever between effects.
That said many parts of it are very good. There's far too many to list them all, but look out for the shade bobs (these must be one of the best ever implementations), the voxelscape, and in particular the lightsourced 3D objects, phew. The music is also consistently good.
Much of this demo doesn't work on a StrongArm at all, so those sections are bypassed if you've got the fast processor. It's a shame that they couldn't have been fixed, though, particularly as this was included on the StrongArm CD-Rom.
If you can survive the gigantic download, this is worth a look. Unique.
