Hmm... I think that would be a whole image in itself, that would need some 
serious work!

It already has that kind of distortion, but I have deliberately avoided 
creating features that would make it too obvious (such as the cloud passing 
overhead in that photo). It also helps that my vertical field of view is a 
lot smaller (in fact it's 380/5=76 degrees!) so the most distorted areas 
aren't visible. IMO it's more impressive to make an image appear 
un-distorted when using a distorted lens, i.e. there's no way you should be 
able to see 380 degrees on a flat monitor without distortion, but I've done 
it :)
