Lego NXT and leJOS

I've always loved the Logo kits in my childhood.. now they are back with a bang with LEGO NXT, all they have is a 32-bit micrprocesssor, huge memory, 3 servos and loads of sensors to play around. but the programming interface is really child-like with drag n drop, and people are not gonna sit around with that, there comes a new hack, the lego software is replaced by a Java virtual machine firm ware and the code can be written in Java. "leJOS".
