Possibly the simplest kaleidoscope we have all seen, but I think it came out pretty neat. I was experimenting with circles and came across this. The longer you watch it, the cooler it looks in my opinion. What do you all think? 24 lines of code. lol
Code: (Select All) 'Kaleidoscope by SierraKen
'May 18, 2022
Screen _NewImage(800, 800, 32)
_Title "Kaleidoscope by SierraKen"
Randomize Timer
cc = 1
Do
_Limit 25
If c <> 0 Then cc = c
c = Rnd * 360
If c < cc Then
s = -.25
Else
s = .25
End If
cl1 = Int(Rnd * 200) + 1
cl2 = Int(Rnd * 200) + 1
cl3 = Int(Rnd * 200) + 1
For t = cc To c Step s
x = (Sin(t) * t) + 400
y = (Cos(t) * t) + 400
Circle (x, y), 2, _RGB32(cl1, cl2, cl3)
Next t
Loop Until InKey$ = Chr$(27)

Nice work, Ken
This works fine with my Windows11.

That reminds me of Mennonite's Rotan:

Do
For y2 = 200 To 1 Step -10
c = c + .04
For d = 1 To 0 Step -1
For a = -3.14 + c To 3.14 + c Step .125 / 8
r = 40 + Tan((a + c) * 7) * 4
x = r * Cos(a)
y = r * Sin(a)
Circle (x + 320, y + 240), 4, 1
r = 40 + Tan((a + c) * 7) * 4
x = r * Cos(a)
y = r * Sin(a)
Circle (x + 320, y + 240), 2, 11 * d
Next a
t = Timer
If d = 1 Then
Do 'repeat 'from
If InKey$ = Chr$(27) Then 'remove $ on functions
End
End If
Loop Until t > Timer + .125 / 4 Or t < Timer - .125 / 4
'WAIT &H3DA, 8
End If
Next d
Next
Loop
Of which, Walter did a nice mod:

Awesome B+. Reminds me of RotoZoom, which I tried with this but I didn't want to wear out my computer on every loop with FREEIMAGE and COPYIMAGE.

That's really cool artwork Rick! I don't know much about _PaletteColor but it looks interesting.

Thanks Ken, I hope to do some more of those.
If you want to do a quick mod of my code, I don't mind. It's just a mental exercise to me.
