Directions and parts lists on this "tensegrity" LEGO construction are ubiquitous on the internet,
but at the current price point of $10 I posit this is worth it for the amount of time you save. I
actually purchased all of the necessary LEGO parts separately (including some redundant cosmetic
pieces). Though the cost of the individual pieces easily adds up to under $10, you'll spend time
finding and identifying the necessary pieces. Rule of thumb is pieces cost $5 so you really are
paying for the convenience of Alan Wong doing all the legwork for you. Fairly easy to put together
if you're a LEGO enthusiast, but nothing tricky for others. And since you get the bonus card case
this is one of those items that's fairly priced.
