Heres a function I made the other night that draws moving fuzzy circles. You can get quite a range of effects by altering the parameters. ;GLOBAL ARRAYS NEEDED Dim fuzzer(10, 360), fuzzdir(10, 360) ;---------------------------------------------------------------------; ;*************************** DEMO ******************************; ;---------------------------------------------------------------------; Graphics 1024, 768 SetBuffer BackBuffer() SeedRnd MilliSecs() Color 200, 50, 50 FUZZ_INIT(1, 100, 360) FUZZ_INIT(2, 100, 360) FUZZ_INIT(3, 100, 360) FUZZ_INIT(4, 100, 360) FUZZ_INIT(5, 100, 360) While Not KeyHit(1) Cls FUZZY_CIRCLE(1, 300, 300, 100, 160, 50, 0, 5) FUZZY_CIRCLE(2, 800, 500, 100, 360, 50, 5, 0) FUZZY_CIRCLE(3, 550, 200, 50, 50, 40, 3, 0) FUZZY_CIRCLE(4, 550, 200, 50, 50, 10, 1, 0) FUZZY_CIRCLE(5, 400, 600, 100, 20, 10, 1, 0) Flip Wend ;---------------------------------------------------------------------; ;*********************** FUNCTIONS ****************************; ;---------------------------------------------------------------------; Function FUZZ_INIT(number, intense, fuzz) For i = 1 To fuzz fuzzer(number, i) = Rand(0, intense) Next End Function ;------------------------------; Function FUZZY_CIRCLE(number, cx, cy, rad, fuzz, intense, vibration, randy) angstep# = Float(360) / Float(fuzz) first_x = (cx - (rad +fuzzer(number, 1)) Cos(deg#)) first_y = (cy - (rad +fuzzer(number, 1)) * Sin(deg#)) this_x = (cx - (rad +fuzzer(number, 1)) * Cos(deg#)) this_y = (cy - (rad +fuzzer(number, 1)) * Sin(deg#)) FUZZ_MOVE(number, 1, intense, vibration, randy) LockBuffer For i = 2 To fuzz deg# = deg# + angstep# last_x = this_x last_y = this_y FUZZ_MOVE(number, i, intense, vibration, randy) this_x = (cx - (rad +fuzzer(number, i)) * Cos(deg#)) this_y = (cy - (rad +fuzzer(number, i)) * Sin(deg#)) Line last_x, last_y, this_x, this_y Next Line this_x, this_y, first_x, first_y UnlockBuffer End Function ;-------------------------------; Function FUZZ_MOVE(number, i, intense, vibration, randy) If fuzzdir(number, i) = 0 fuzzer(number, i) = fuzzer(number, i) + vibration +Rand(0, randy) Else fuzzer(number, i) = fuzzer(number, i) - vibration -Rand(0, randy) EndIf If fuzzer(number, i) >= intense fuzzdir(number, i) = 1 Else If fuzzer(number, i) <= -intense fuzzdir(number, i) =0 EndIf End Function --v

shroom_monk	Yeh, that's cool. But you seemed to have missed off the End Function command from the end, which I had to add on in order for it to run.
