I hurt myself at the gym and am feeling the stress from keeping so many balls in the air at once. My solution is generally either a shower or LEGO. Since my blocks are mostly in storage, I looked into downloading LEGO Digital Designer, LEGO's official virtual tool, and Bricksmith, a less-polished but more useful independent program with an extensive library of pieces. The latter will feel familiar if you've ever used Google's Sketchup or any other bare-bones 3D software.
If I can't run my hands through a box of LEGO in person, I'll happily settle for this instead. It takes me an hour just to place one brick but I'm practicing putting up walls efficiently using the Clone tool. I'd like to build a temple or a mausoleum.
