The Lego Mouse certainly doesn’t look like it’s comfortable to use, but if it’s Lego, who cares, right? The fact that you have a giant Lego brick tethered to your computer should make up for whatever discomfort you’ll feel, not to mention you’ll also make the kids incredibly jealous. The only downside that we can see is that it’s available only in red, but if you’re cool with red, then be prepared to shell out $31 for it.
