What is this

[Davckowski]

I seem to be finding theese strange zig zag tracks on the glass more and more often. I try not to hit them with the alge magnet and the go away after 5-6 days. I'm sorry the pics were taken with a cell phone camera they almost look like eggs? At first I thought it wa some kind of worm because it seems to move and grow but I'm not sure. Anyone know?
