Made by BLUTUE Sand in a bottle... YAY! -Hold your mouse over the "bottle" to drop sand into it. -Pressing and holding the Space Bar will stop the sand flow. -Use the left and right arrow keys to change the color of the sand.
If you are experiencing lag you can try the new "Change the amount of stuff on my screen so that my poor PC wont fry itself" mode. Because Im too lazy to use phosphorous. By pressing the green flag twice you can enter this mode. What it does: shows FPS if you are experiencing lag the program will slow down the rate that the sand comes out of your mouse to reduce lag. Its not perfect but its something.
