Japanese wave pattern - Yellow by Firefox user 11981622

A simple black/yellow pattern I made for Thunderbird. I got the pattern from <a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/1ea0ad85d380932b32550263edb88823e05152fcf7833ea4b1059d23c0b4c41a/http%3A//publicdomainvectors.org" rel="nofollow">http://publicdomainvectors.org</a> and just changed the background colour and size.
