I made a T-shirt with the EURion constellation on it. It did work, kind of, but not as well as I liked - distance and angle mattered a lot.&lt;p&gt;My original goal was to wear it for official documentation, but that went less well. It was cut off in my drivers license photo, and I forget why, but I never ended up wearing it for passport photos.&lt;p&gt;&lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;en.wikipedia.org&amp;#x2F;wiki&amp;#x2F;EURion_constellation&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;en.wikipedia.org&amp;#x2F;wiki&amp;#x2F;EURion_constellation&lt;/a&gt;</text></comment>
