The Dofi-Blog sand and zombie toys are making their way around the Web like a ??? explosion (inside joke), and for good reason: they are quite literally sandbox games that allow for a seemingly infinite variety of creative play.
And now the author, d_of_i, has released another sand world, Hell of Sand, which appears to be a combination of the previously reviewed War of the Hell and World of Sand. There is even a large version (pictured) for those with faster computers.
In this one, the little zombie people cling to the rolling ball as they did the spider's thread in War of the Hell. What is the point you ask? Nothing more than pure creative entertainment for the imagination.
As with the previously reviewed Dofi-Blog interactive toys, this was also made with Processing, which is built upon Java. Therefore, your computer must have at least Java v1.3—ideally v1.4—installed to view and play with them. Although Java v1.5 may work, the Processing folks have this to say about Java v1.5: "...We don't support it and recommend that you avoid using it, as we don't test with it and it appears that it may be the slowest (certainly most bloated) release of Java yet."
Regardless of your Java install, do give this one a try. If it works, kiss the day goodbye.
