Can't keep your kid's nose out of his Nintendo DS? You might tempt him to give the video games a rest with a paper model from Paper Toys. Most parents will have to stay involved in these projects, as they can get quite complicated (and require a certain level of manual dexterity), but there's enough here to choose fromeverything from a T-Rex to the Taj Mahalto keep your craft table humming for weekends to come. The models are provided as one-page letter-sized printouts on your home printer; the site suggests using a photocopier to enlarge. For more retro fun, check out FlipClips, where you can turn your 30-sec. home video into a 150-page flip book for $19 (smaller books cost less). You submit your footage using the site's easy drag-and-drop upload tool; the site accepts most major file formats, and gives advice on what to do if your file is too big (more than 25 MB).
