ɹǝpuɐz.com or How to Buy an International Domain Name
I just bought this domain for myself, it currently points to this blog and I love the geekiness of it but my wife thinks otherwise!
If you want to get your own upside-down or otherwise (✿.com / ♫♫.com) domain name then head on over to John Sutherland’s blog post, How to register an International Domain Name for instructions on how to do it. I also highly recommend domainsite.com for buying these domain names, they’re super cheap!
