QUBEX  Honestly, Red Pill is better, and it's free. No guilt trips either.

MR. HAPPY PANTS  Bahhh, don't listen to ol' grumpy pants. This is a great screensaver and I personally don't mind the developer's 'reminder' that his hard work is worth money. The demo works long enough for you to realize that this saver ROCKS!! Be your own judge and don't be put off so easily by all the Grumpy-Pants-Hyper-Critics floating around.

GRRRR!  The screensaver looks pretty nice, except for the lack of "fog" effects that many of the other FREE Matrix screensavers offer. The part that sucks is that the moment you install this screensaver and it begins to display, you get bombarded with THE MOST ANNOYING BUY ME! BUY ME! BUY ME! MESSAGES. This really only serves to piss the user off and so he uninstalls it without even a moment's consideration about shelling out eight bucks. Well, that's what happens with greedy software developers. They're so afraid you'll enjoy their toy for more than a FLEETING MOMENT so that they end up spoiling it for themselves. BUY THIS? NO WAY?

Message to developer! Give people a chance to learn to like your screensaver. Leave them in peace for JUST TEN MINUTES to enjoy these visuals, then introduce a polite onscreen suggestion to purchase your product.
