The LEGO Magic Lantern can cast blurry yet discernible images onto your wall, making it an incredibly engaging and entertaining build for you and your curious child.
Styled like a lantern, the contraption has a lens on the front that shoots images out onto any wall, using the light from your smartphone. Given its fixed focal length, the projector does need to be adjusted to ensure the image on the wall isn't blurry or washed out.
