Change position of shapes drawn in sketch, without affecting future shapes drawn on mousePressed

Hey! I am trying to create a sketch where the user draws circles, and, after a set amount of time, the previously drawn circles' y position changes.

I tried a variable that subtracted .01 each loop, but that lowered the position of all future circles as well. Is there any way to only specify the position of circles already drawn?

Thanks for reading and for any advice!
2. boolean brushOn = false;
3. float moveY = 0;
4. void setup() {
5. size(500, 300);
6. background(#FFFFFF);
7. } //end setup
9. void draw() {
10. moveY = moveY + .01;
11. if(brushOn == true){
12. fill(#000000, 70);
13. ellipse(pmouseX, pmouseY + moveY, 40, 40);
14. }
15. } //end draw
17. void mousePressed(){
18. brushOn = true; //start drawing when pressed
19. }
21. void mouseReleased(){
22. brushOn = false; //stop drawing when released
23. }

Export drawing with blur

I attempted to export a drawing to pdf after using filter(BLUR, 6);

I got an error and assumed it was because blurs couldn't be exported into a vector. Then I tried to output it to .dxf, but ended up with a zero kb .dxf file that wont open in autocad. I changed to mode to OPENGL and others, but the file is still 0kb.

Is there any way I can export my drawing from processing into a still image/vector while using this filter?

Here's my file:
