DNA; the building blocks of life!
This would probably be one of the most awesome fan-made concept art for any intellectual property.
Stanislav Ushakov has created a line of products that would make any LEGO fan easily lust after. The LED torch might not seem to be the best in terms of execution but I can easily see how the keychain might be a big hit.
Simple yet impressive is how I would describe this product line of dreams. Shut up and take my money!
