All Pixels All the Time
I spent some time yesterday browsing the shop of another member of The Handmade Forum: PuffyTheSlayer. The owner, Rhi Louise, bills herself as the geek with the creative streak. And creative she certainly is.
Her pixel art jewelry is both fun and fascinating and, once I got over my envy (she lives in London, for heavens sake!), I found lots of things that might be the perfect holiday or birthday gift for a geek in your family.
I think her Pixelated People fridge magnets are especially cool as is the fact that, if you buy one, it comes with Citizenship in Pixelville.
Do visit her shop — you will have fun and maybe find something just right for you.
