For several months, earthnite and I have been working on a project called TI-FLOW, which is a port of Flow Free to the TI-84. Most of the information pertaining to this project is available on this thread at Cemetech. It is nearly finished, but we would like your opinion regarding the cursor:
The TI-FLOW cursor can operate in one of two ways, always blinking, or only blinking when a flow is not selected. With the first option (always) it is easier to keep track of where the cursor is and where you last clicked, but movement with the line is slightly slower. With the second option (sometimes), it is more difficult to keep track of the cursor and where you last clicked, but movement with the line is slightly faster. The second option also takes an additional four bytes of code.
