hi all, it was idea: try to create tetris on lists, destructively and without grid from simul.l
current code: https://bitbucket.org/mihailp/tankfeeder/src/2a5c18b2694c641564298c34f6aed7842019ae35/citris/?at=default playground: 1. move.l - use arrow keys to move object inside world 2. roll.l - rolling all possible objects inside world https://imgur.com/4JelKp9 I have to stop here, rest are trivial and boring :) Mike
