FA artist Jaleo once created a series of badges with national flags as backgrounds. I persuaded him to make me a high resolution image in similar style. Czech company called SkinBook made me a sticker from it and I have it on my laptop ever since. So I'm proudly wawing not only the Czech national flag, but also my furry self as well.
I'm quite often speaking publicly, on development and e-government related conferences and I'm always presenting my laptop, showing this proudly to the audience. Makes exceptional conversation topic!
