Kaleidoscope - Drawing by lines
Draw lines with color number set by generated random numbers.
Each time you run it, the pattern on the diagram changes.
Sub Kaleidoscope()
Dim i, c, dx
monhdc = GetForegroundWindow()
myhdc = GetDC(monhdc)
If myhdc = 0 Then Exit Sub
InitializeGraphics
Randomize (Val(Right$(Time$, 2)))
dx = Int(Rnd(1) * 10)
For i = 0 To 199 Step dx + 2
c = QBColor(Int(Rnd(1) * 16))
Call DrawLine(i, 0, 199 - i, 199, c)
Call DrawLine(399 - i, 0, 200 + i, 199, c)
Call DrawLine(i, 399, 199 - i, 200, c)
Call DrawLine(399 - i, 399, 200 + i, 200, c)
Next i
dx = dx \ 2
For i = 0 To 199 Step dx + 2
c = QBColor(Int(Rnd(1) * 16))
Call DrawLine(0, 199 - i, 199, i, c)
Call DrawLine(200, i, 399, 199 - i, c)
Call DrawLine(0, 200 + i, 199, 399 - i, c)
Call DrawLine(399, 200 + i, 200, 399 - i, c)
Next i
End Sub
