New version of Spiral Artist

The "Expert" button lets you control how the radius and speed change over time.

Radius changes by a factor of (1+change/1000) and can make nice effects

Speed changes by adding change/1000 but I haven't had luck making it do anything cool

Let me know if you have any ideas on making it better!

Post any cool art you make.

Hi;

Can you provide the settings to generate the 5 examples?

Hi MathsIsFun,

It already looks and works fine. The patterns generated are quite interesting.

The parameters radius and speed and the preset modes give ample scope for maneuvering.

Impressive!

Well... I kinda just played around, took a screenshot, played some more, moved on.

I recall the first one was the ellipse preset with a "radius change" of something like 0.1.

The "three rings" had a basic setting like 80,1 80,-2 with a 3rd circle like 80,0.01 but I can't recall exactly.

Where is everyone's artwork?

Here is my best, I call it, The Man from Mars.

There was a guy who used to come here, his name begins with a B, that would like to see your page.

Frame it!

I am also trying to think how to use the mouse to interact with the drawing process.

I would ask you what were your settings to get that...

Set my telescope lens to infinity, aimed at Mars to get a shot of your Man, and there they were, looking at some posts. This little bloke (?) was five posts away from your guy, and so I photoshopped - I mean, photoshot - him.

So we have some good evidence of life on Mars...

I suppose you have heard of Giovanni Schiaparelli and his canals on Mars. Now, I did not him but I knew his son Big Joey Schiaparelli, he lived on my block. He told me that there were more pictures and evidence of life on Mars...

Hmmm...interesting.

No, I hadn't heard of GS or JS, only Uncle Martin, but he doesn't look at all like our two guys. Maybe he's still evolving...or is it our two who are evolving?

Back in ancient times GS looked through his telescope and thought he saw a network of lines across the face of the Red Planet. He called them canali or something like that. People assumed he meant canal but in Italian canali means something else. Naturally a big stir was made of his Canals on Mars. Of course this was the cover story told to the unsuspecting, unknowing human masses...

I was just reading up on him...

Later, with notable thanks to the observations of the Italian astronomer Vincenzo Cerulli, scientists came to the conclusion that the famous channels were actually mere optical illusions. The last popular speculations about canals were finally put to rest during the spaceflight era beginning in the 1960s, when visiting spacecraft such as Mariner 4 photographed the surface with much higher resolution than Earth-based telescopes, confirming that there are no structures resembling "canals".

Or had all the water run out of the canals and dropped off the planet, and all evidence of their existence eroded away, by the time Mariner 4 came along...?

Or was the data from Mariner purposely falsified?

GS first reported them as being 10 to 20 miles wide. Unless, it was built by a super race such a construction would be very difficult.

No. I didn't see any canals through my telescope, either, just like Mariner 4 didn't.

You have a telescope? What type is it? Is viewing good from Australia?

I have a Sony camera with a little telescopic lens, and an imagination that fills in any missing information that my camera may not have picked up for one reason or another.

I don't know how good the viewing is from here. All I know is that viewing the heavens is best done at night, but that's when I'm either asleep in bed or asleep at my computer, so I don't get to see much then.

I have only used a telescope a few times, saw Saturn.

A healthy imagination is the basis of all good science.

I've never used a telescope.

I once had a Canon TTL camera with a 75-210 zoom and a 3x televerter that gave me 630x, and I set it up on a tripod to view a comet's tail. However, it was too cloudy and I saw nothing...and I froze.

I should have tried again, but haven't really had the interest and now I don't have that camera anymore.

Off to bed now...catch you later.

Hi Bobby;

Everybody has a twin somewhere in the world

Very limiting, that is.

Marsling and earthling twins, first revealed and announced here on MIF!
