ScreenMelting.cpp

#include <Windows.h>

int main() {
	int inc;
	int sw = GetSystemMetrics(SM_CXSCREEN);
	int sh = GetSystemMetrics(SM_CYSCREEN);
	
	while(1)
	{
		inc++;
		int x = rand() % (sw - 0);
		int w = rand() % (5 - 0);
		int y = inc;
		
		HDC hdc = GetDC(HWND_DESKTOP);
		BitBlt(hdc, x, y, w, sw, hdc, x, 0, SRCCOPY);
		Sleep(100);
	}
}

For some reason it only works if compiled as 64-bit
