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

  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
