Every day here, we talk about Windows customization. Skinning the Windows UI, changing icons, tweaking performance, adding animation, giving everything a different look and feel. However, there's an entire world of customization out there beyond your PC.
In the past, I've posted about cool case modifications, hand-made mice, weird desks etc. We've seen all the cool stuff OTHER people do, but I'm wondering what all YOU do that isn't Windows skinning.
Do you mod your car? PC case? Build strange lawn ornaments? Let us know what else in your life you customize, tweak or otherwise make your own in a unique and interesting way. If you have photos, post them! (But please, keep them clean)
