Time left , visual warning

Hi,
I have been trying to write a code to get a visual waning on the screen when there are 15seconds remaining in the time fame in use.
I have a code wherein the time left is indicated in the title, in yellow, a screenshot is pasted below.

The code I am using is below :-


_SECTION_BEGIN("Title Time Left");

SetChartOptions(0,chartHideQuoteMarker,chartShowDates);
GraphLabelDecimals = 2;
GraphXSpace = 10;


function GetSecondNum()
{
Time = Now( 4 );
Seconds = int( Time % 100 );
Minutes = int( Time / 100 % 100 );
Hours = int( Time / 10000 % 100 );
SecondNum = int( Hours * 60 * 60 + Minutes * 60 + Seconds );
return SecondNum;
}

RequestTimedRefresh( 1 );
TimeFrame = Interval();
SecNumber = GetSecondNum();
SecsLeft	= SecNumber - int( SecNumber / TimeFrame ) * TimeFrame;
SecsToGo	= TimeFrame - SecsLeft;
if( Status("action") == actionIndicator ) 

( Title = EncodeColor(colorBlue)+ "Name()" + " - " +  Name() + " - " + EncodeColor(colorRed)+ Interval(2) + EncodeColor(colorYellow)+" || " +WriteVal(SecsToGo,0)+" ||"
+ EncodeColor(colorGreen) + "  || " +  Date() + " ||" +EncodeColor(colorBlack)+ 

StrFormat(" Op =  %g  | Hi = %g  | Lo = %g  |  Cl = %g  ", O,H,L,C)+ EncodeColor(colorGold)+"  |  OI =  "+WriteVal(OI,0)+ EncodeColor(colorBlue)+"  |  Volume =  "+WriteVal(V,0));


Plot( (C), "Close", ParamColor("Color", colorDefault ),GetPriceStyle());
_SECTION_END();

Instead of staring at the time left in the title is it possible to have some sort of flashing message on the screen?

Thanks in advance

oops, "Instead of staring at the time left in the title is it possible to have some sort of flashing message on the screen, Thanks in advance" - not part of the code ,only what I have been trying to acheive.

if (LastValue(Open) < LastValue(Close))
GfxSetTextColor(ColorRGB(117, 237, 16));
else
GfxSetTextColor(ColorBlend(colorRed, colorWhite, 0.3));
GfxSelectFont( "Tahoma",15, 800 );
GfxTextOut( ""+WriteVal(SecsToGo,0),100, 100);
